Oh MAN. You opened a huge can of worms right there.
Whoops!
The issue is that she is radicalizing a lot of her fans, and the UK already has too many TERFs (there are that many that they are attacking laws protecting trans people and preventing laws that would protect trans people)
Basically this. A lot a young people, or parents of young people who read her books, follow her on Twitter and see make her well-written, rational-sounding arguments like "sex is real", and then they see people insulting her in the replies. Surely those rude people must be wrong, and the nice lady author they like is right? If some random person spouts hate online, that's their problem. But if someone with a huge platform uses it to spread hate and lies about a vulnerable group, that's when it becomes a problem for everyone. In my opinion at least.
Anyway. Here's an official art of Sakura Quest's (remember that anime? it was a fun watch) Maki and Sanae that got lost in the upload queue. The author of the manga adaptation shipped them. Loved the domestic roommates-to-lovers vibe they gave off. Might try requesting an upload again, I dunno.
