As others have said, we often make fun of ourselves. On these platforms, the liberal side of America is very vocal about the conservative side of America. Healthcare, guns, cost of living, etc. are something we’re constantly being made fun of (often from ourselves).
If you’ve experienced pushback, it’s likely because it gets stale as a subject. We know our country has problem; most of us feel powerless to change it.
Maybe that’s what happens when you have this much diversity in a country. We’re not like the French who can all unify and protest when needed.
edit: Rereading this, it makes it sound like I think diversity is a bad thing. Didn’t mean to imply that, its just that we’re so different its harder to unify.
