I believe that you can have internalized hate, yes. For instance, when I was 10/11 I thought it was really cool of me to say things like “You throw like a girl!”. I thought that by me trashing my gender, I was getting brownie points from others. Like, “Look how cool she is! She admits girls can’t throw!”
But in reality I was just participating in self deprecating behavior. I really did believe that girls couldn’t throw. The notion that girls can’t throw is a misogynistic one, and because it was coming from me, a girl, it’s internalized. Not only was I being misogynistic to other girls, but also to myself.
That’s the definition of hate/prejudice being internalized. When you hate/are prejudiced against the group you’re included in.
You may not even notice you’re doing it. In fact, most people with internalized hate don’t know they have internalized hate. The thing is, many people think that because they’re part of the group they’re trashing, it’s okay. But it’s not. It just means you’re trashing everyone including yourself, which is actually worse. Often times it’s a learned behavior. I heard boys saying girl’s can’t throw, so I repeated it to gain approval. I don’t know when I stopped doing that, but I’m happy I did.
