I mean if they have read some of his stories, it should be pretty obvious he was pretty fucking racist. The cat thing is a fun meme but if anyone has read at least call of Cthulhu the work most people know about its pretty on the nose. Every human antagonist is either black or a foreigner and he is pretty blatant about it. Hell don’t get me started on Facts Concerning the Late Arthur Jermyn and His Family (or The White Ape), that one is just so funny with how bloody racist it is because the conclusion is so absurd, you can’t take it serious.
