To your point on Trump, his supporters are a diverse group, most don't believe what the media reports on him (see: the media blindly repeating the government's lie that the economy is doing fine), and those that do genuinely believe it will solve their problems thanks to decades of suffering and not ever being helped by more positive policies.
To your second point, not really. The most misogynist groups believe Harris has been running the country since Biden more or less admitted he was unfit for office. They've internalized that a woman is currently president. If a woman wholly unrelated to the Biden campaign came out swinging against biden and Trump while acknowledging the dem party's failures, she would have won, in a landslide. There would definitely be holdouts, but theyre never going to vote dem.
Why do you people think you could negotiate with Harris? Biden and the Dems leadership have done nothing but override popular positions. The beloved vp of the Harris campaign, the most progressive actual dem to ever run for that position, fucking called the military on civilians instead of doing anything about police brutality in his state.
Also if you're willing to accept genocide on the idea you might be spared if you do, you're a Nazi. That was the Nazi excuse. "We need to kill them so we can be spared."
