I now feel compelled to explain myself. My use of it was only in a secondary remark, non important for the main point of my post. And I think somebody versed in the nuances of sex work advocacy may have heard of this concept too. If not, well, not much loss.

Interesting that you caught SJW and missed virtue signaling. This is more obscure I think and, admittedly, it was a part of my main point. So, from google:

the action or practice of publicly expressing opinions or sentiments intended to demonstrate one's good character or the moral correctness of one's position on a particular issue.
