I have no problem with narrow-mindedness, as long as I don't have to have it forced on me. I don't even have a problem with Christian bigots (as one example) who might not approve of gays. If they don't like these people, they shouldn't have to permit them into their homes. But if they want to start denying people fundamental rights on the basis of sexual orientation, that's something entirely different.

Same with cops. I have no problem with them living their boring, conventional suburban lifestyles with their bake sales and their little league games and their sunday barbeques. But if they put on that uniform, they need to leave their personal prejudices behind when they walk out the door, and stop coming up with ridiculous theories like such-and-such person was probably the serial killer "because he was a loner."
