Agree to Disagree

Don’t act like your opinion is the only one that matters.  Unless your opinion is “The Holocaust was really, really bad,” it’s possible to have valid, opposing viewpoints.  Not everyone has to agree with you.  The fact that someone has a differing opinion doesn’t make that person an asshole.  Arguing for the sake of arguing with someone who wants to agree to disagree, however, could make you an asshole.
