If you think of bigotry as a germ or some other infectious disease vector, we live in an amazingly sanitized society. That’s not to say it doesn’t exist, of course. And we can all debate how prevalent it is later. My point is that the institutions — the organs of the body politic — that are the most obsessed with eradicating bigotry (as liberals define it) tend to be the places that have to worry about it the least. The Democratic party is consumed with institutionalized angst about prejudice, intolerance, and bigotry in America. But the odds are that relatively few of these people (particularly those under the age of 50) have been exposed to much real racism or intolerance.
