I, for one can't wait 'til there's a "Political" forum.
I used to get into these arguments on here a bit, but I now prefer to just have fun and stay out of it. Few, if any minds have been changed here.
I often discuss politics with my guitar player over a cigar (for me, he doesn't smoke, he just drinks) a shot and beer. Though we're both Liberatarians, I tend to play devil's advocate to stir the pot. It can get heated, but never negative. And we both end up laughing at the end of each topic.
I think when you take away the up close and personal like in a forum such as this, you open things up to get a lot more heated vs. friendly disagreement.
Then again, maybe you're all just jerks. { =^ )
Whatever floats your boat, I guess. (That's the Liberatarian Mantra BTW)
