I really think people who are not posting anything here but JK Rowling posts should be discouraged if not a rule made for it. I think an overwhelming portion of the fan base disagree with or at least are aware of her opinions on trans people.
I like HP, I like HP memes and JK won’t see another cent from me. Which sucked because I wanted to play legends due to never getting any real solid HP games as a kid. That said, I would like a HP community that isn’t plagued with these sort of post though.
