mg,
It looks to me like you are a little bit sensitive to the perspective of some of our fellow posters.
I don't see anything particularly obnoxious about the variety of viewpoints in this thread but that doesn't make your reaction any less valid in my mind.

I would not be bothered if the posters you see as rude and offensive paraded in front of my house (or in the middle of whatever threads I happen to be following)or through the main street of my hometown.
It's a matter of context.
This forum tiff means nothing to me because I'm an unaffected outsider--sort of like some of us are outsiders to the thread topic and no matter what our notions are or how ready we may be to judge, what we have are the perceptions our imagination provides.
That's not the same as real experience.

Would it bother you if you knew there was a certain weekend that the posters who've ruffled your feathers would bring their friends and march up and down your road? Would you detest a celebration marking the day they pissed you off enough for you to be completely done with them?
Would you hate feeling like they were making a big show of rubbing your face in it?
