Wise words

A man of uncommon wisdom, Thomas Sowell:

Individuals and groups of all sorts have always differed from one another in many ways, throughout centuries of history and in countries around the world. Left to themselves, people tend to sort themselves out into communities of like-minded neighbors.

This has been so obvious that only the intelligentsia could misconstrue it — and only ideologues could devote themselves to crusading against people's efforts to live and associate with other people who share their values and habits.
Quite aside from the question of whose values and habits may be better is the question of the effects of people living cheek by jowl with other people who put very different values on noise, politeness, education and other things that make for good or bad relations between neighbors. People with children to protect are especially concerned about who lives next door or down the street.

But such mundane matters often get brushed aside by ideological crusaders out to change the world to fit their own vision. When the world fails to conform to their vision, then it seems obvious to the ideologues that it is the world that is wrong, not that their vision is uninformed or unrealistic.
