If it helps, the game itself is very positive about the whole spectrum of human sexuality and treats everything as completely ordinary and it’s all represented (trans included), like the Wizarding world has already come out on the other side and everyone is welcome.
I think JK very purposely tried to tarnish it so that less people would play it, she already got her cut from the licensing, so sales don’t matter to her.
The game itself is exactly what we want and what she would hate. The company that made the game is someone we should support, they took the world away from her, fixed it, and gave it back to us.
