Do these jerks actually believe real Americans give a crap what they think?
They probably do believe people care what they think (wrongly).
A few years ago, when I was in grad school at SF State, a European I knew was on a long, U.S. bashing rant (culture, values, policy, etc.) and asked me "Don't Americans know what we think of you?" The person never spoke to me again after I answered "Where did Europeans get the idea that we actually care what you think?"
