I came across a Twitter thread, and the general idea is the goblins and orcs in Tolkien's works are based off racism and antisemitism. I'm from Malaysia, English is my second language, and I can't relate to the points made in the thread because I have limited knowledge of dark-skinned orcs being a racist caricature of Africans. I have read the trilogy many times, and not once has it ever crossed my mind to associate orcs with Africans. I don't even see Africans as ape-like or anything that is mentioned in the thread. Are they really based off racism and antisemitism? Please help. Thank you in advance.
