Hatred is used to control the public. The more the wealthy can make you hate, the more they can keep you under their thumb. Because when you hate you are blind. You are stupid. You are manic. You are emotional. You are not driven by reason, logic or compassion. So you will not vote for socialism.
The only thing that matters to the wealthy is making sure you do not vote for socialism. So they will make you hate. They will make you hate whites, blacks, browns, women, men, gays, transsexuals, straights, jews, chinese, russians, eskimos, immigrants or anyone else. They'll just make you hate so you never focus on socialism.
So long as you hate then you will always blame someone else for your crimes other than "the rich". Whether it's "white privilege", or "filthy niggers", or "spic immigrants", or "the leftists", or "the jews". Your hatred will always make you susceptible to blame a scapegoat for your suffering instead of blaming rich, rightwing capitalists. So hate is peddled to everyone in order to protect these rich, rightwing capitalists.
Your hate is your chain which binds you. It is the shackles upon your heart and upon your soul and in order to ever be free you must release yourself from it.
