Saw this thread, and it really hit a chord with me, as these similar fears tend to constantly weigh on me (for various reasons- being trans, ethnic Chinese, commie, etc).
I think we all (leftists, but also just most minorities) know, shit is bad and will get worse, it's just a question of how bad it will get. People mention it offhand without usually going further into the details, and similarly in other spaces - non-leftist ones as well, for instance Asian diasporic and LGBT spaces in my experience, these fears come up, but ultimately we keep the bulk of our concerns to ourselves. What are our expectations here, for the west? Not just for the US, but the Anglosphere and Europe?
The Nazis never won an actual majority even in manipulated elections. 75% is absolutely enough to go full third Reich.
Jews were less than 1% of the population in prewar Germany
They didn't only go after Jewish people though, they also attacked the various traveller peoples living in Germany, gay people, leftists and dozens of other relatively small groups.
I realize, but if you add up everyone they targeted it wasn't 1 in 4 people.
