It's practically every country man. There's always weird othering (racism is just one category) and a belief that xyz is better than abc. There's tons of pockets everywhere. Some cultures are just harsher than others at how they effect the "others" they believe they are superior to.

It doesn't seem like it matters which side of the political spectrum they're on either... deep down there's always a belief even on an individual level that we're better than others in some way because of some bullshit rationale probably driven by evolutionary instinct that drives competition and propagation of genes one might consider "similar" to their own. At least that's a rough idea of how I think of it, because like everything it's complicated.
