Ok last thought about the Harper's letter:

The sheer number of signatories who have waded into the transgender debate on the anti-trans side is astounding. I read many of the references to specific gripes in the letter's text as specifically directed at trans critics.

These folks have argued for a whole host of restrictions on transgender people's lives, claiming that they must see thorough debate. Classifying the fight for trans rights not as a policy debate, but a crucible of fire through which the trans rights movement can emerge stronger.

They utterly denounce mere twitter disagreement, painting trans critics as overly aggressive and misogynist.

But! When you step back and view the wider world that exists beyond their twitter bubble, you see a completely different dynamic of censorship regarding trans issues.

Last year, the most challenged book in American libraries was George, a book about a young transgender girl. http://www.ala.org/advocacy/bbooks/frequentlychallengedbooks/top10

Here is the Amazon description of George’s plot. Utterly innoceous.

The rest of the ALA's top 6 most challenged books also have transgender themes. and 2 of the other top 10 have LGBTQ themes.

Ironically, the only two on the list which aren't challenged because of queer themes are Harry Potter and The Handmaid's Tale.

The point is that these people think of themselves as brave truth tellers, not afraid to slay the transgender dragon with their words. But when you remove them from twitter discourse, it quickly becomes apparent that they are the dragons themselves, backed by the power of society

I would challenge each of the 150 signatories, even the trans woman, to look around their workplaces and count the number of trans people (or Black people ftm) employed there, much less in a position of power. If you truly believe in free speech, you would see an issue there.
