Well, I'll admit it.
I still go to Culver's regularly, but seldom venture far from the "Gun Talk" forum. That forum is still friendly and accepting of diverse views. But it's mostly about "light" politics and news stories.
It stays good-natured and most of the participants seem to be good guys.
(I hope I didn't just poison the water there.)
But once you venture into the specialized forums, you're kinda on your own. Those forums are where you'll find the hard-headed and self-proclaimed "experts" holding their ground. Some very knowledgeable folks are there, but there always seem to be challenges from someone.
Edit:
Well, my slow typing put me in line behind Chuckindenver but he just posted my thoughts very nicely.
