If the election were between Trump and somehow someone even worse who was calling to nuke the entire area and turn it into glass, then I would absolutely be pushing for Trump.

It does not get worse than genocide. The habit of inventing a hypothetical bigger and harder gun to hold to marginalized peoples' heads doesn't work on this one.

Shockingly, if we are trapped in a horrifying, dystopian version of the trolley problem (which we are), I'm going to make the choice that causes the least damage.

We are not trapped in a trolley problem. You are a human with agency. You can join organizations, you can educate, you can take action. Reducing your political agency to a lever pull for genocide is a helplessness taught to you by the political class because they just want you to vote for them even when they commit genocide right in front of your eyes. They want you to think of Palestinian lives as strategically expendable and that you are actually smart, not racist, for toeing that line. And your compliance with their demands is exactly what ensures they can shove any monster down your throat as a candidate. Harris is complicit in genocide and didn't win a single primary but Dems say, "well, time to fall in line". Dems strategists know that "progressive" Dems do this so they do nothing for them in policy, they just deploy PR goons to vote against every 4 years. Compliant voters enable their own irrelevance.

Though of course, voting is very limited and there is much more to be done.

Using another analogy

I refuse to entertain analogies justifying genocide.
