Do you actually know that switching from "Mother's Day" and "Father's Day" to "Parents' Day" has anything to do with trans people? Without the context of your comment I would have guessed it was more about (1) trying not to upset children who have lost a parent, (2) trying not to upset or confuse children who've never had two parents around, and/or (3) trying not to upset or confuse children brought up by same-sex couples.

Of course you might consider any or all of those to be Stupid Woke Nonsense, but whether right or wrong, sensible or stupid, they're not about trans people.
