There were some things I really endorsed and others where I said no way, I'm not going to follow that. I don't believe that. I think that's part of the human condition. The problem is that these beliefs and values are largely not amenable to rational persuasion. You don't talk somebody out of their beliefs, because these are held with passion.
People are ready often to die for what they believe in.
I see this in the medical arena, for example, with Jehovah's Witnesses who believe blood products to be unacceptable and who will say that they are willing to suffer for the sake of that belief, even if the consequence of not getting blood products is death. That's preferable to consciously betraying their convictions. This gets us back into the area of the limits of respect for beliefs and values that may be quite different from those in the mainstream. The most dramatic example of that I can think of has to do with female genital mutilation. There are groups, cultural and religious, who believe this is a good thing to do that it enhances the desirability of the woman or the girl, that it makes her a better marriage prospect.
