Dr. Don: I agree with your sentiment, and frankly, it's a disappointing side to any message board site. I think there are many dynamics at play here causing such a sometimes caustic atmosphere.
1. Zero personal accountability: What are people going to do to me for posting negative inflammatory comments?
2. Anonymity: No one knows me, so I feel safe to voice my true feelings and bar no holds.
3. The nature of the beast: This is a message board. Opinions are voiced here, whether they're good/bad, rude/polite, dumb/intelligent.
4. It's an outlet: Where else can we vent our feelings of frustration/delight and hope/despair?
5. Bad manners: Gonna sound a little self-righteous here, but some folks just don't choose to watch their tongue. Bad habit. Oooh, that sounds really self-righteous, but hey, it's a message board, so I'll get flamed, but that's the premise of my statement, so what else should I expect? I don't think my car will get keyed, cause no one knows who I am, and my opinion is just as valid as the next guy's, so hey, I'm free to be self-righteous. It's a message board!
Go Gophers! Just try and be nice about it!
