Dude I know it's fanart but that's why it is annoying to see people do this to characters that wouldn't do this and using the excuse that their not real the same excuse lolicons use also shirou really does care bro have you even read or watched fate? He legit admires Rin and would do anything to protect her and he sees her being raped he wouldn't just stand there he'd protect her , shirou cares for Rin to say he doesn't care about the fact she's getting raped in this fanart is a complete misunderstanding of his character if he sees anyone in danger or trouble of any kind he'd help her and these fanart depict him observing Rin tohsaka being raped by a black man.
Holy shit dude take meds or better go see a doctor you can't understand the difference between fiction and reality.
I really don't understand why people are so upset with this, as far as I know, lolis have existed even before I found this website. If you don't like the aesthetic then just don't interact with it. No one needs to get called something vile just from a piece of art, and as far as I know, movies and tv shows were the one who exploit children and they are rarely getting called out.
