I have 2 good friends that are on the complete opposite end of the political spectrum from me. For whatever reason, we get along well, and all of our conversations about politics are civil. (Come to think of it, most of our conversations ARE about politics, which is weird that we consistently begin conversations that we know we will disagree on.)
Maybe we just have similar "Debator" personality types...
To clarify, it isn't that I necessarily think people are defined by their political views; it's just that we tend to gravitate towards people with common interests.
How about you? Does having opposing political views make it hard to be friends with someone? Anyone have very different views from their spouse?
