You guys realize that the definition that you all use (racism = power + prejudice) is being taken as the right thing only on tumblr? Anytime I have heard black person saying ‘I am black, I can’t be racist against white people’ everyone was looking at them with real concern on their faces, wondering if they are joking. Congratulations tumblr activists, you actually stick to something that normal people consider to be a joke.
normal people? i think you mean ignorant people, not “normal”. i hope you get a chance to take a few sociology classes so you can learn more about why racism = prejudice + power.
