I do believe people still vote for dictatorship if they think it will fuck over others much harder, then themselves, and "they deserve it".
I think it's very important that people continue to recon with the fact that millions of Germans voted for Hilter and supported his rise to power despite because he wanted to enact antisemitic policies.
He also did a coup, so there's that.
Can you tell us more what you have in mind? Nobody who voted for Hitler in the early 1930 are still alive today.
