can someone fill me in please, I missed the while situation save a couple memes.

Pedro Pascal’s sister is a trans woman. He has been publicly very vocal on the subject of trans rights and inclusion. Consequently, a lot of transphobes, chuds, and miscellaneous fascists have been targeting him for a while and trying to smear his reputation any way they can. I don’t really pay much attention to celebrity stuff so I don’t know to what extent JK Rowling is personally involved in that, but given that she has been a very outspoken anti-trans bigot for some time, I would not be surprised to learn she was egging her followers on to that end.
