This sort of churning around of words happens all over our culture, not just academia. Back in ~1985 when I was in school it became not ok to say retarded as that is derogatory , and there was shift to use the word "Special". Immediately then "special" become derogatory.

Anyway this is normal human stuff that is always going on, its a bit silly, but its also fine. Find other battles to get irritated about that matter, is my advice.
