I enjoy Jim Gaffigan, the comedian. Yes, once you've watched his specials repeatedly, you see the patterns in his subject matter. But I enjoy him a lot.

During one bit he says this as a prelude to the main joke:

A woman can grow a baby inside their body. And then somehow a woman can deliver a baby through their body. And then by some miracle a woman can feed a baby with their body.

"Their"? I know he is speaking as we have all been forced to speak. But even when the sex of the person in question is quite known and unavoidable, he can not say "her." Again, this is commonplace these days. But what is really sad is that no part of him cringes; no part of him recognizes the hideous solecism.

You can argue that language changes. So, yes, the loss of the generic "he" is leading to a loss, too, of sex-specificity in pronouns, at least for abstract males and females. So language happens. Language is what people speak. But it is truly a loss when a "woman" is no longer a "she" but is just another "they."

Anyhow, resist this nonsense. If you can't bring yourself to use the generic "he" when the sex is unspecified (and if you can't, you're silly), at least use the sex-specific pronoun that is appropriate to a subject that is clearly male or female.
