That has nothing to do with "hate speech" and is just sold to Americans like that. Critisism and hate speech are entirely diffferent things and US's adminsitration is just.. idk insane lately?
In EU, specifically Germany, its very different. You can critique publicly all day every day all politicians, dead or alive, as much as you want to and nobody is allowed to even give you a mean stare.
But you can't spread hate or directly specifically offend someone, but surely comment on their performance during their mandate.
