It surely is. Caring about language (caring about anything, really) is an honest signal of status, whether you like it or not. Inevitably, some people will try to slave-moralize it away. If some social/ethnic/sex/... minority with inferiority complexes jumps on this bandwagon, suddenly you may find yourself caring about a thing whose ignorance some social scientists somewhere have found to be correlated with holy cows.

Proposed solution: stop caring about everything besides making all people feel good about themselves.
