Benevolence is a curious creature. Its operation tends to be more beneficent the more specific it is. This was a point that James Fitzjames Stephen, the great nineteenth-century critic of John Stuart Mill, made in his book Liberty, Equality, Fraternity:
The man who works from himself outwards, [Stephen wrote] whose conduct is governed by ordinary motives, and who acts with a view to his own advantage and the advantage of those who are connected with himself in definite, assignable ways, produces in the ordinary course of things much more happiness to others than a moral Don Quixote who is always liable to sacrifice himself and his neighbors. On the other hand, a man who has a disinterested love of the human racethat is to say, who has got a fixed idea about some way of providing for the management of the concerns of mankindis an unaccountable person who is capable of making his love for men in general the ground of all sorts of violence against men in particular.
Political correctness tends to breed the sort of unaccountability that Stephen warns against. At its center is a union of abstract benevolence, which takes mankind as a whole for its object, with rigid moralism. It is a toxic, misery-producing brew.
