I hear ya Mark.
That's one of my mantras, which is basically the second posting rule here, about never ever criticizing the speaker, only commenting on your perception of the logic behind what he says. I have to say, and it's not a comment on anything specifically here or DD or whatever that different people want different levels of engagement and intensity in discussing that logic. For instance, again if I'm talking with my wife, a lot of the time she just wants acknowledgement of what she said, that that's her opinion, and not have everything totally scrutinized and challenged. And I have lots of real friends that fit in with this and online friends that fit in with this
On the other hand I have real friends that, like me, prefer to get into an animated discussions and online friends that fit in with this. And certainly, for me, I think I'm sensitive enough, but perhaps not, to engage in both types of discussion. Sometimes the second one is definitely inappropriate even if non-threatening cause it can just give everyone a headache. The second type can, I would say more easily generate into road rage, but at this state of my life (Very busy) that's why I only enter into it, basically, with trusted friends. Again at this stage of my life I'm not trying to change the world, I'm just trying to get the kid off to school and the mortgage paid down.
So I guess this can also serve as clarification that there is a difference between the animated discussions that I have had the privelege to enjoy with my friends, and the road rage or Fox shouting matches or shock radio and TV that painew keeps alluding to. For the record, I haven't watched or listened to five seconds of HOward Stern or any other shock TV personality. Again I'm totally in support of your rule number two, so much so that if I were ever to sponsor my own website (when I retire

) I'd probably use it word for word.
Anyway I do also understand Paine's concern 'bout not givin' everyone a headache
Cheers!
