Yes, that was hilarious. Very accurate as well.
It does seem to me that as Americans we are more forgiving of racially insensitive remarks towards foreigners or peolple of foreign descent. Whereas with blacks, women, or homosexuals we consider them "one of us", so we treat any degoratory remarks towards people of these groups more harshly. I would guess its partly because people of such foreign descent are still primarily viewed as "outsiders", and therefore we aren't really as concerned with their feelings in a somewhat subconsious manner.
