I'm mostly in agreement.

I don't know what words are to be the new curse words. Apparently "retarded" is headed that way, which I find especially ironic considering that it was taught to me as the polite alternative, but of course it is not quite a general purpose word - and such a word should probably be a single syllable anyway for maximum effect. It is probably still "fuck" for the moment, but perhaps a new contender that I don't know about is in the wings.
