I'm only just catching up with this person. I didn't know Gray was even part of this organisation, even in the role of patron.
As far as I was concerned, Gray was a smutty comic who took the piss out of their own transgenderism. Writing stuff where they threaten a co-worker with a hate crime, that sort of thing.
It's notable that transgenderism is so often associated with adult sexual performance.
Linking it to children in any way is dodgy (imo).
