Ok there's a difference here, and the difference is effect.
I like HP Lovecraft's work and he was a racist piece of shit.
I liked Harry Potter and JK is a transphobic piece of shit.
But HP is dead and his stuff is public domain so none of my money goes to racist organizations.
If I bought any Harry Potter stuff, some of that money would go to JK who uses that money to fuck over trans people.
No one is saying you can't enjoy Harry Potter, and it's wild to think that you can't imagine enjoying something without buying it.
If I really wanted to reread the stories, I'd pirate them or borrow them from a library. Same with the games. JK won't get a dime from me and hasn't in a long, long time.
If people like Harry Potter, I don't judge them poorly, but if they are buying it now, I do judge them.
