SP,
Having just bowed out of a thread like that, I know exactly what you mean. In my case, often it's a simple matter of wanting people to realize when they are being, at the least, judgemental. Not that their opinion is going to change, but at least recognize that they want to impose a very personal opinion on other people. One of my goals in life is to have my own ideas and opinions, while recognizing that others have the same right.
I think there are those capable of debating well, without resorting to name calling, but unfortunately those cases are few and far between. And to often, discussions can turn into rude innuendos and off topic rhetoric.
On the other hand, wouldn't life (and this board) be quite boring without some of the passionate opinions expressed?
