I don't want to discuss politics or religion in forums where people only want to discuss politics or religion.
To the point I want to have such discussions (which differs from time to time), I prefer to have them with people with whom I know I share other connections.
I'm not a politics or religion junkie...and don't want the level of passion, anger, fear, and loathing those junkies generate. I like it that on the GDP, when we venture into those horrible subjects for awhile, and vent, at the end we can always say "well screw that...now, is that an Em7 there or a G?"
I too get drawn into some of these discussions against my better judgment, almost with a sense of dread – but it remains entirely true that we can avoid threads we find unpleasant.
Finally (yeah, I bet!), while it's an accepted maxim that no one's mind is ever changed in those threads, I know from experience that even intense and pointed discussions, if conducted with basic civility, goodwill, and mutual respect, can change minds. My own mind has been changed on numerous occasions, and I've heard from members who say they think about something differently based on something I've said.
So even when the discussions veer into rancor and get testier than we like, I think on the GDP they often have value.
