Actual leftists KNEW that already. Kamala, Biden, the majority of the DNC - they’re all corrupt corporatists.
But the situation the USA was in was one of minimizing overall damage. And with the corporatists, there was still a small chance of gaining some control from them peacefully via elections, if simply because more left leaning people can at least run under the Democrat moniker.
With the fascists, that opportunity is gone. By allowing them to win, not only do you worsen the genocide occuring in Israel (if not ensured Israel from achieving it entirely), but also just got killed a bunch of other people and hurt a huge amount of minorities in the USA as well.
Not voting didn’t stop the genocide and never would have, but it did guarantee that it gets worse while hurting other innocents outside of Palestine as well. If you didn’t vote for Kamala (which literally means “horrible” in Finnish), you’re a dumbass, because you allowed a greater evil to prevail. Especially since I know many of y’all abstainers are still paying taxes anyway and funding the genocides either way.
If most of the world is against a thing, asking if said thing might be bad isn’t asking “tough questions”
