What the fuck is wrong with those people?!

I've now been in the great United States of America for about 4 days and so far it has been a relatively pleasant experience. However, one big issue stands out and it ties back to what I talked about earlier...
So far, I've been "mm-hmm":ed roughly 4-5 times and the pace has intensified the last couple of days even though my own research through a statistically significant poll shows that over 65% think that it's not an acceptable response under any circumstances. This is what's wrong with this nation, not the war or anything else, that's just symptoms of the disease!
