The difference is, when Russia and dumb US citizens say "Ukraine is a Nazis state" 1) they are outright lying and 2) Russians do not think of "Nazis" as meaning the same as what the rest of the world understands. Russians do not hate the Nazis for being genociding freaks, they hate them for being backstabbers.
Weev meanwhile is just a fucking Nazi. This exact thread is about a person who is not a Nazi facing persecution, and yet you go out of your way to use a literal and explicit Nazi as your example.
In fact, nearly every time I see people make this kind of "Oh it could happen to you, it happened to <X>" they seem to pick people who are damn Nazis.
Gee, I wonder why those are the cases they know about?
