We need to build some real social stigma around being afraid of cities. You don't have to like them or live there, but a politics built this strongly around watching TV and going "ewww" is embarrassing, and people should be embarrassed by it. It's like "fear of werewolves" being your top issue.

Never forget the same people defending pedophilia have spent years trying to convince the public that drag queens and trans people are a threat to children.

This is inside baseball, but to me, there are three ways in which this development *bears out* Justice Jackson's unusual intervention Friday night—about which there was much confusion.
First, this makes it clear that a majority of the Court was *not* going to force the USDA to fund SNAP by Friday.

The right-wing think tank which wrote the entire platform for the current president of the US is defending neo-Nazis, and meanwhile a substantial portion of American rabbis think the Muslim candidate for NYC mayor who has denounced antisemitism is the biggest threat to me as an American Jew.

Christian Zionists often profess to love both Israel and the Jewish people, but for many of them, this devotion is intrinsically tied to their beliefs about the fate of the Jews in the end times—and it’s not pretty.

In light of the PSF's recent loss of an NSF grant and attendant funding shortfall, I will be matching donations up to $5000. Send me your receipts.
Very happy if you've already donated for similar reasons but the point is to motivate *new* donations so be sure the timestamp is after this toot 😉.

Once again, the main day of Tea Party protests had about 300,000 nationwide, but saw endless coverage.
The No Kings protests had about 7,000,000 nationwide, and many media outlets reacted with a yawn.
No Kings was nearly 25x as big as the Tea Party but the Tea Party got 25x the attention.

Ask yourself this: How would the New York Times have covered the protests if it had been seven million MAGA supporters flooding the streets? We don’t even have to guess: We know how they and other mainstream outlets covered the Tea Party protests during Obama’s first term.
