They don't look like having had enough any time soon. The antagonists in the culture wars all seem to share two assumptions. One is that American society really is in a state of increasing fragmentation, that groups which once happily assimilated are now refusing, and are likely to continue to refuse, to melt. The trouble with this faith is that in addition to being socially and economically mobile and unstable, modern liberal societies are culturally mobile and unstable, as well. A new taste means a new market.
Liberals can only stake the survival of their philosophy on a guess.
The guess is that the cultural antagonisms that look like a new and dangerous tribalism are simply the epiphenomena, the shaking out, of an irreversible process of integration in American life. Contrary to most assertions, American society is becoming much less like a mosaic and much more like a can of mixed paint. The life-paths of women and men, and, to a lesser extent, of black and white Americans, are more likely to be congruent than at any time in history. Friction is not, after all, the consequence of separation. For everyone's combination must be different.
