I agree, and add that I don't meet a lot of people period. lol Also, the people I do know in real life aren't very eager to discuss a lot of the hot issues. Not to mention that cm gives me a much wider variety of viewpoints than I could ever encounter in real life.
I've had some great conversation in here, even when we're disagreeing. Conversations that wouldn't be polite in a general social setting, or that were simply absurd by still entertaining. I'm not here consistently, and yet no one says I shouldn't participate (as I've seen happen in other groups). I appreciate that.
