It entirely depends on how much they respect your point of view. If it's a personal belief, then yeah, I'm friends with people who old opposing points of view on a number of issues that I consider important.

If, OTOH, they are of the "my POV is the only right choice, anybody who thinks otherwise is morally deficient and should be shot" school of thought then that becomes more tricky.

Particularly when they try to shoot you. Friends don't train firearms on friends.
