I don’t think that’s true. Most people are willing to extend a good bit of grace, especially if there’s already a relationship worth preserving.

As in, if I just met someone and I know nothing about them other than they don’t like unions then we probably won’t be friends but if that came up later I’m not going to blow up a year of friendship over something like that.

OTOH if a friend started preaching white supremacy that would do it but I’d give a good shot to talking them out of it first.
