I don't think so: those are strong convictions that people have according to their value system and moral code and it's their right to have them. I'm not talking about that at all. To me, those are "closed handed" issues: we respect them without negotiation.

I'm talking about "open handed" issues where people tend to debate and negotiate: preferences, not convictions—if 3/4 friends want to go get a sandwich, but 1/4 insists on either salad or "go without me", this can be taxing on the relationship—especially if they also are usually open to sandwiches and have no strong conviction against it.
