Because the number of people you're suggesting executing, for one. And because their ideology is not actually Nazism, for two. And because the thing theyre doing does not actually contribute to the genocide in any material way BECAUSE AS YOU ADMIT YOURSELF VOTING DOES NOTHING. AND because in their mind, as hard as it is for some of you to get this, they arent supporting genocide. They're resigned to the fact that the genocide is happening no matter what they do, and trying to improve material conditions in other ways. They're wrong about this, lesser evil voting doesn't work (and we really need a master post as to why btw, or a ProleWiki page about it). But this is the way our ENTIRE FUCKING CULTURE has gaslit us into thinking about elections and its VVERY FUCKIGN DIFFICULT to break out of it. If you're one of the very small number of people who never thought this way about US elections, congratulations. You somehow avoided the conditioning. But the rest of us didn't.
I was a lesser evilist about voting up until Oct 7 last year pretty much lol. And I was a communist way, way before that. Its not an easy mindset to break out of. These people are not Nazis.
