I have the opposite - a childhood friend who is a flaming liberal, and extremely vocal on FB about it. Politics aside, she's a great person with a huge heart, so I just skip reading her stuff when I can tell it is something I'm opposed to. But again, I am extremely tolerant of other opinions, unlike the DUmmies. What's perhaps the better story, is that an old friend from college has "united" two of his friends in political debate - they've never met in person, but I know them both, and they debate each other after having noticed each other on my friend's FB page. They're both extreme in their views, but they debate each other in a very civil manner. It is pretty amusing.
