My opinion (for what it's worth) .... only when you have the right to express your opinion openly in approximately equal measure is it an equal type relationship, so if you truly want to have a fairly close relationship with her, then the only way to do so is allowing yourself to express your beliefs, or at least the right to request that she express her beliefs less often and less forcefully. Having done that, the ball is now in her court to decide if she cares for you and respects you enough to hear what you say and behave accordingly. Hope it smooths over quickly and that things are better once that has happened!
