I’d say people fall somewhere in between 0% and 100% bigoted and what they will tolerate/laugh at can be incredibly nuanced. Nobody is actually 0% or 100% racist but I generally consider myself “not bigoted” in a broad sense. Everyone is of course carrying some bigoted opinion(s) though, it’s unavoidable.
But back to the point: I’d say I am by and large not particularly bigoted. Still, I’d be lying if I said I have never laughed at off-color jokes. No matter how progressive or anti-racist you are something is going to break through. That is what makes it such a powerful tool for less scrupulous actors. You find what a person or community is willing to tolerate, then you either peel off people in private or push boundaries out loud and slowly drive a wedge into the community.
