Being friends with someone doesn't mean we both should agree on everything. It also doesn't mean we should try to avoid discussing whatever. If we agree on something, good. If someone is changing his opinion bases on a talk and arguments, good. If not, also good.

I am friend with someone because I like that someone and I enjoy meeting him and talking to him, doing things together.

That doesn't mean agreeing on everything. And doesn't mean being afraid of speaking.

If someone quits, being my friend because we have different opinions on X, so be it. I am not like that. I won't break a friendship because someone thinks differently.
