Every time I interact with American tourists or travel to the US, 90% of the interactions I have with these people end in an argument is some other unpleasant experience. They seem to get really upset if you say something either a.) they don't agree with or b.) they don't understand. While other cultures have people that just brush these things off and turn the other cheek, Americans seem to be extremely vengeful and emotional, wishing bad things on people that they, again, either don't agree with or don't understand. Most of the time it's annoying but sometimes it gets scary (during my last trip, some black guy started mumbling profanities at me because I was speaking another language to someone).
I do not notice this behavior with other cultures. Americans are the only ones who do this.
Has anyone else here had a similar experience with Americans? Is it something to do with their notoriously bad parenting/schooling or is it more of a medical illness? Is it safe to safe that most Americans have ASPD?
