Most Trump voters I have come across don't actually know what fascism is, so the insult dosnt work. They still believe they are voting for small government and lower taxes, they are in a delusion and they can't believe otherwise regardless of what I would call facts.
Trump voters are quite practiced at mentally cherry picking what their dogma is in their religion, so for them it's not as much of a stretch.
I've had to switch to grayjay for YouTube recently I don't know what they do differently, but it seems to work better with vpns than newpipe. Works about 80% of the time where newpipe was more like 20%
