Firstly, all respect to those of nonbinary gender identity. Represent by selecting C (or applicable poll response) and commenting to weigh in.
Also; I do not deride SJWs. I'm more than qualified as one myself. It just makes sense for us all to ask one another to maintain healthy standards of political correctness, AND of simple interpersonal respect.
It's the mark of the true SJW, though, to hold oneself to consistent standards, and to admit it when one lapses. It erodes our good name when we over-enforce, or when we simply deny our mistakes.
This question is about first-world nuisances. Hope most of us regard it as a necessary nuisance when someone counter-intuitively corrects you on someone else's pronoun preferences (i. e. when you're told not to call that hottie in form-fitting jeans "her"). Stay on watch for those personal pronoun preferences.
And it makes sense to say "they" if you know an individual specifically prefers you to. And it's okay to say "they" if you lack knowledge of an individual's gender identity, or especially if you don't know her/his/their actual gender. (Note my example of the articulate solution. It's rarely asking too much to write or to say "he, she, or they.")
Whereas the trend of PRONOUN OVERWATCH is an unnecessary nuisance. If you know someone likes to be called "her/she" and someone else likes to be called "he/him," then why say "them/they?"
When I noted that this bothers me, it felt like healthy emotional self-honesty. It soon got me wondering if maybe being bothered is more of a guy thing, so I decided I might as well poll. I considered polling women only, but realized there's no reason not to keep it open to all.
