We had an unexpected snowstorm last night, dropping less than an inch but still covering the ground, as it’s below freezing. Fortunately the weather has warmed up today.

Armon and Vashti were starving this morning because of the cold, and were waiting for me at the “feeding spot” at the north end of Botany Pond.  They had a huge breakfast, and gave me the gift of their tracks in the snow. This is the only way I know they walk around on the ground when I’m not there.

I can’t get enough of Duck Tracks in the Snow.  In fact, that would be a good title for a song. . .

Since I was in an upsetting kerfuffle with the Freedom from Religion Foundation (FFRF, and I call the squabble “The KerFFRFle”), over which I resigned from its Honorary Board along with Steve Pinker and Richard Dawkins, I haven’t paid much attention to the organization. I do get their alerts, for they’re still doing good work in upholding the First Amendment’s Establishment Clause, reinforcing the wall between church and state. Their condemnations, like the one I highlight here, don’t usually accomplish much, but their lawsuits or amicus briefs have been effective, and the FFRF does raise awareness about Constitutional violations.  Yes, they are overly woke, which is why I resigned (see the first link), but that doesn’t mean that their overall effect is bad. It isn’t!

I noticed the other day that they’ve gone after New York City’s new mayor, Zohran Mamdani, who I see as both an antisemite and an Islamist. And by “Islamist” I mean a Muslim who is active in trying to make countries adopt Islam as part of their system of governance.  In this case, Mamdani is mixing Islamic religious celebrations with city business: a violation of the First Amendment. I have little doubt that he would like the U.S. to become the Islamic Republic of America.

An excerpt:

The Freedom From Religion Foundation is again warning New York City’s mayor that the Constitution prohibits government officials from using the machinery of public office.

FFRF has sent its second letter in a couple of months to Mayor Zohran Mamdani after receiving a complaint from a New York City employee regarding a recent religious event organized through official city channels. The national state/church watchdog previously contacted Mamdani in February after he posted on the official New York City Mayor’s X account about participating in a suhoor meal and praying with Department of Sanitation workers during Ramadan. [JAC: he appears to have deleted the tweet, and if that’s the FFRF’s doing, good for them],

Despite that warning, FFRF has now learned that the mayor’s office held a “City Workers Iftar” on March 12 to “celebrate workers who keep New York City running while fasting.” The event notice was emailed to city employees by Interim Commissioner Melissa Hester and it noted that the event included a call to prayer.

A city employee who contacted FFRF observed that it is “completely inappropriate for a government agency to have a religious celebration.” The employee expressed concern that events like this may create the perception that the mayor’s office favors one religion and that employees attending city-sponsored events may be expected to participate in religious activities.

“While you are entitled to observe your faith in your personal capacity, the Constitution prohibits government officials from organizing, promoting or participating in religious exercises in their official roles,” FFRF Legal Counsel Chris Line writes to Mamdani. “Hosting a religious observance for city employees of one religion and facilitating a call to prayer through official government communications and personnel crosses the line between private religious expression and government-sponsored religious worship.”

FFRF emphasizes that city employees work under the authority of elected leadership, creating a dynamic where even “voluntary” religious events can carry implicit pressure. “Public employees should not be placed in a position where they may feel compelled to attend a religious event or appear supportive of a particular faith tradition to maintain favor with their employer,” the letter states.

I oppose Mamdani not only because of his Islamism and apparent antisemitism, but because he’s a faux Democrat, promising much but likely to deliver little. (See his latest gaffe on St. Patrick’s day!) And I worry that because the Democrats are so befuddled and besotted by “oppressor/victim” ideology (Mamdani, being a Muslim, is seen as “oppressed”), he will have a future in politics beyond being mayor. He could become a Congressman, though fortunately not President, as he wasn’t born in the U.S.

Anyway, be aware of what’s going on in NYC, and kudos to the FFRF.

Greek mythology has given a name to a great many objects in our solar system. But perhaps one of the least well understood are the Trojans, named after the people of Troy featured in The Iliad. When astronomers refer to them, they are normally talking about a group of over 10,000 confirmed asteroids orbiting at the Lagrange points both in front of and behind Jupiter on its orbit around the Sun. But, more generally, astronomers can now use the term to refer to any co-orbital setup - indeed almost every planet in our solar system has Trojans, though not as many as Jupiter. Which also leads to the belief that “exotrojans” must exist around other stars. Despite our best efforts with initiatives like the TROY project, so far we have yet to find one. But a new paper published in The Astrophysical Journal by Jackson Taylor of West Virginia University and an abundance of co-authors took the hunt to one of the most extreme environments in the universe: pulsar binary systems.

Today’s Jesus and Mo strip, called “Minor 2” came with a note that it’s “a resurrection today, from the more innocent time of 2007.”

This is a good strip because it makes the point that the claims of many “standard” religions, when laid out in black and shown to someone who hasn’t been religious, seem just as silly as the claims of Scientology, which do involve Xenu, space travel, volcanoes, and hydrogen bombs. (They don’t tell that to novice Scientologists.) For example, Wikpedia lays out the beliefs of Scientology in its “Xenu” article:

Xenu (/ˈziːnuː/ ZEE-noo), also called Xemu, is a figure in the Church of Scientology‘s secret “Advanced Technology”, an esoteric teaching held sacred by adherents.  According to the “Technology”, Xenu was the extraterrestrial ruler of a “Galactic Confederacy” who brought billions of his people to Earth (then known as “Teegeeack”) in a DC-8-like spacecraft 75 million years ago, stacked them around volcanoes, and killed them with hydrogen bombs. Official Scientology scriptures hold that the thetans (immortal spirits) of these aliens adhere to humans, causing spiritual harm.

These events are known within Scientology as “Incident II”, and the traumatic memories associated with them as “The Wall of Fire” or “R6 implant“. The narrative of Xenu is part of Scientologist teachings about extraterrestrial civilizations and alien interventions in earthly events, collectively described as “space opera” by L. Ron Hubbard. Hubbard detailed the story in Operating Thetan level III (OT III) in 1967, warning that the “R6 implant” (past trauma) was “calculated to kill (by pneumonia, etc.) anyone who attempts to solve it”.

The Church of Scientology normally only reveals the Xenu story to members who have completed a lengthy sequence of courses costing large amounts of money.  The church avoids mention of Xenu in public statements and has gone to considerable effort to maintain the story’s confidentiality, including legal action on the grounds of copyright and trade secrecy. Officials of the Church of Scientology widely deny or try to hide the Xenu story. Despite this, much material on Xenu has leaked to the public via court documents and copies of Hubbard’s notes that have been distributed through the Internet.

Scientology has done a lot to try to prevent its dictates from being known, but it’s too late. And those dictates are not that much sillier than the Christian myth of a scared Jesus who was God/Son of God, came to Earth, was killed, came back to life, and ascended to Heaven, with belief in this being helping you to have a pleasant eternal life rather than burning in hell.  Every faith I know of, down to those of Cargo Cults, is based on irrational beliefs or unproven claims about the supernatural (some forms of Buddhism may be exceptions so long as they don’t belief in karma or successive rebirths).

But I digress. Here’s the cartoon:
