If you're around people who might be talking about politics then suddenly turn to you and ask what do you think?

It really depends on who it is and who has said what, because for some friendships (or a work relationship) I'd much rather keep the peace. If I don't care about them, then I'll say my mind. I don't enjoy arguing for its own sake.

I always say something that I know will start a fight, then I just walk away.
