Why do I have this need to be right (for this particular issue) and How do I get rid of this need?

I have a friend, who's a hyper right side. I don't particularly have a side, but I disagree with a lot of Trump policy. I don't want to be political, but I feel like my friend is very hard to get through.

I challenge a lot of political views with my friend, and some of time I think they're down right insane (or not). Either way, why do I have this need that I have to push my view point into my friend's view point?

Why do I have this need to be RIGHT?

A lot of time, I don't bring political issues up and it always lead to some type of political arguments (which is stupid and does nothing to our friendship). I tend to stay away from it, mainly because no good really come out. I either believe 1) their confirmation bias or 2) mine confirmation bias is too strong to overcome. There's really no convincing my friend.

Do you have such need? And how do you overcome it?
