Like they unironically hate 'undesirables' for resenting them for being treated by them with hostility completely unprovoked. Like really, if someone told me I was a bad person for belonging to a certain group I have no control over completely unprovoked, why shouldn't I resent them? The nazi cries out in pain as it strikes you.
In the free and democratic America we're allowed to silence and fire people if they voice their support for an oppressed people undergoing genocide, unlike those ebil gommunist countries where you're forced to sympathize with terrorists!
