Is a bigot a fixed thing, and the definition and "the bigot line" changing with social norms?

I think the point of GUESTDavid's definition is that often there are TWO "bigot lines" - and a tolerant middle ground. Lots of examples around here...

Sorry, I can't agree with either of these statements. Well, OK, the first is a question and the answer is "no". A society can be bigoted. Over time, if the majority of the people in the society move away from that bigotry, it may look like the line has moved, but really the minds of the people have moved.

I really don't think there are two bigotry lines. It's usually pretty clear in my experience. What there are, however, are a lot of people who cry "Bigot!" where bigotry doesn't exist. I've noticed a lot of bigots doing that, sort of seeing themselves in others, perhaps. I've also seen anti-bigots calling someone else a bigot when they really aren't. It's all a matter of treating individuals as individuals.
