What if someone's values and beliefs are that certain other values and beliefs should not be allowed? Like what if a group believes that gay people shouldn't exist openly in society, or that certain racial groups should be genocided or stripped of their rights?

I think this is a fundamental issue of tolerance of beliefs - how do you tolerate intolerant beliefs without sliding into intolerance yourself?
