I don't see any benefit to bigotry either. I guess you could say it's a version of "I may disagree with what you say, but I'll defend the death your right to say it."
And, I think it's a choice. You can refuse to challenge your own beliefs, or those of the people around you. I'd call that either a fear response or shear laziness, depending on the situation. Or, you can choice to examine beliefs and be willing to update them. It might not be a choice that comes easily, but it's a choice.
One of the places I fault our educational system is that it not only doesn't teach or encourage critical thinking very often, it frequently discourages it. Too much emphasis on "THE right answer". I'd rather we spent more time on "here's a problem, how many ways can you find to solve it that work?"
So, I'm not ok with bigotry, but I'm also not ok with a group, any group, deciding they've cornered the market on truth.
