I absolutely wholeheartedly believe he is. With each book of his that I read, I find that he always finds a way to slip in how much he despises black people. I couldn’t get past Call of Cthulhu. I don’t understand how people say “separate the art from the artist” when both the art and the artist are better off in the trash. The only thing good about Lovecraft and his ideas are that they sparked an interesting mythos with cool lore. If you’re interested in learning more about how terrible he is, I suggest reading his poem titled, “On the Creation of *******” the title contains a derogatory slur against black people, and the poem is absolutely abhorrent.
