our existence is a threat to traditional gender roles and family structure. the real thing they fear is "social contagion" - that trans kids will see us living happy lives, and realize they can transition too. they're afraid of gay people for similar reasons, but physical transition is a whole new level - they have a visceral reaction against it, like their innocent child has been irrevocably, physically corrupted.
they realized that using their existing levers of power (cutting off funding, changing curriculum, ID laws etc.) won't do shit: we can DIY hormones, socialize on the internet and look out for each other. so now they become increasingly authoritarian, hence designating us as "domestic extremists" and calling for our forced institutionalization.
the Heritage foundation is handling us like the SCP foundation handles a Keter-class anomaly.
prepare for surveillance of any social groups you belong to, harassment at security checkpoints, detainment if you say anything they can take out of context as evidence of some crime or threat, and random acts of violence. have armed security at any event where large numbers of trans people attend. improve your opsec - switch to Signal, get an iPhone or GrapheneOS, migrate from Discord/Google/Instagram. start carrying a taser and take self-defense classes. put together a bug-out bag. stock up on HRT if you can. don't break any laws, no matter how minor. if you are arrested or detained: comply with orders (under protest), don't tell them your phone PIN, say nothing except "I exercise my right to remain silent and I want an attorney."
it remains to be seen how bad this gets. if they start rounding people up in masse, we'll all need to flee and request asylum.
good luck.
