Yeah, maybe? Humans do tend to do dumb things because other people are doing it. Mob mentality is one version of it. I’m sure seeing other people downvoted could trigger others to see the negative first, therefore downvote.

Not to mention sheer numbers. Like, the higher EU user numbers are, the more people you might find that would defend EU & see USA more critically than Americans would. Just like in an American user heavy server, you might expect to find more users that would start defending USA & lashing out at other countries.
