My guess is that this semi dude is someone from alt.moose or alt.tasteless who's started contributing to this group to bait us into responding. The same thing happened about 6 mos ago on rec.pets.cats and probably goes on in most of the other newsgroups. Bascially, they can't stand that anyone is emotionally wrapped up in something they don't care about, so they have to get on a newsgroup and act obnoxious. That's my theory anyway.
