Can you get along with someone with very different political views?

My friends know my political ideology or ideals or whatever you want to call them. Not because I am an outspoken person who hands out literature or lectures them when given the chance, but because outside of of little core social circle I have found myself becoming increasingly politically active, and with Facebook, knowledge (and tagged photos) tend to spread quickly.

Recently a friend has started dating a guy with a very different political perspective. Somewhere along the line he clued in our figured out my political affiliation, and since then, he will not shut up about it. Every opportunity, to him, is an excuse to turn something political- I cannot buy a sandwich without this guy turning it into an accusation or an argument. I can't suggest a book or film to a friend without being told it is propaganda. I am open for some political discussion, I'm not open to being interrogated on my values while I try to have a drink.

He does not scream or anything- he picks it up rather coyly and naturally, even if the situation had nothing to do with politics.

The friend tells me to just bear it, and that her boyfriend is just opinionated. She cites me being politically active, but I make a great effort to keep my politics separate from my social life, and it's not as if I'm a candidate or a revolutionary- I attend some rallies, and help out at some organizations. This guy would have you think I'm planning to run for office!

I never initiated this apparent political rivalry, and friendly outings have turned into this guy's charismatic soapbox.

I feel like his rants are diving our peaceful group- it's become very us vs. them, and politics have suddenly become an ugly and present issue. There's a time and place for debate... coffee after a long day is not always it.

I don't need this stress right now.
