op is acting as if it's only america that's made fun of
litterally everything in existence has been made fun of at least once.
there's people who say "all black people are bad and are no-life criminals" and that are actually serious, there's people who make fun of german people, french people, dutch people, turkish people, asian people, and lots more. all because of their stereotypes. if you can't handle it you might want to return to your fantasy world where this doesn't happen lol
EDIT: oh oops didn't see this already turned into a religion argument from something completely unrelated
