I am reminded of how the KPD getting its leaders murdered by Freikorps thugs during the Spartacist uprising

These Freikorps thugs were sent by the SPD. It's in the interest of both liberals and conservatives to fight leftists, both liberalism and conservatism are rightwing, capitalist, imperialist and deeply chauvinist ideologies, one is just more focussed on hegemonial control and the other more on open violence. You cannot fight for queer liberation, or the rights of any other marginalized group such as America's black community, immigrants or indigenous peoples, with Bidenite Democrats, the last 4 years with its constant onslaught of anti-queer and especially anti-trans legislation (and also the uninterrupted continuation of an ever brutalizing border regime and the steady increase of police militarization) have proven this. The only Democrat opposition to trans genocide we've seen in that timeframe has been on the state level, by individual actors, the Democrats as a federal-level institution are downright scared of being too openly supportive of trans rights, Clinton as a prototypical member of the DNC establishment has more or less stated that she views our rights as a fringe issue that poses a political liability and Biden has only started voicing support for trans people when election season went into full swing.

I'm not telling Americans not to vote for Biden in November, i honestly may do so if i was Amerikan, but i'd probably do so by mail-in ballot from abroad because if i would live in Amerika, my top priority would be to get the fuck out. These are the reasonable options for US trans people, either leaving the country or work on community organizing and prepare for mass civil unrest, because mass civil unrest is the only thing that will stop the clericofascist mob. Biden won't do that, or he would have put more effort into clamping down on a movement that tried a coup and wanted to murder leading members of his party when he got into office. He's too comfortable with fascism to actually stop it, and he doesn't even meaningfully stall it.

So yes, i'm worried about the trans-exterminationist agenda of the US far right, it's a main political concern of mine because it directly affects my life even here in Europe that Reaganite nazi orgs like the Heritage Foundation are actively financing and supporting anti-trans activism here. But none of this has gotten better under Biden, and he will not change that, because he needs a continued threat to marginalized people to browbeat them into voting for him. Democrats are not allies. All they have to offer is a false sense of safety, the illusion that you can vote yourself out of the existential threat that Republicans already pose. You can't. You can try stalling for four more years, sure, but has that stalling actually worked in the last 4? And even if Biden wins the election, will he be able to govern afterwards or will there be another coup attempt that may work better this time?

When you focus on electoralism as the core strategy, you're playing the wrong game. There is no safe option to vote for trans rights in the US. The American left needs to prepare for worst case scenarios instead of putting its hopes in an eroding system that never was designed to serve their interests in the first place. There needs to be real thought put into all possible outcomes, what to do under another Biden term, what to do when Trump gets elected and what to do when he steals the election, and all of these scenarios are dire for trans people and require strategies that lie outside electoral politics.
