It's funny how you can really enjoy someone's company until you find out their political views - can just ruin everything so fast..
I'm fine with differing views. The world would be mighty boring if we all agree on everything. What I'm not fine with is the outright dismissal of everyone who disagrees with you. I have several good friends who I nearly completely and totally disagree with politically. We know it and we simply don't let it come up. We like each other, we respect each others' views, and we simply don't let it come between us.
