It's kind of a fascinating concept that all human behavior could be the result of a parasite in the brain, including all our differences and ideologies. Like everything that makes you "you" is just because of a brain worm. Being parasitepilled, I know it's true that parasites can and will affect human behavior when infested. But to think that all of humanity is initially infected with a special brand of parasite is a frightening thought.
The parasites don’t need to be in your brain to affect your behaviour.
We don’t know that everyone is under strong parasite influence. A lot of people are though, and in most Western nations we don’t do regular parasite cleanses so those people get worse and spread it.
