I used to think this line of thinking was dangerous and was going to help Trump win reelection. But I think you're right, we can't let the threat of a Republican being elected coerce into supporting a genocide.
The only clear answer is to teach the Democrats they need to hear and listen to us and champion our policies. The only way I can see to do that is to throw my support entirely behind Donald Trump and other Republican candidates up and down the ballot.
Maybe once only right wing candidates are winning the Democrats will learn that the only way to power is to run extremely left wing candidates and we'll finally see some progress.
You're right, I'm voting for Trump now because of the Biden genocide. If he didn't want to lose the election he shouldn't have supported Israel or tried to close the border. I honestly don't even care what happens to Palestinians under Trump, Biden should have thought about that before hand.
