How do you stop being ashamed of your race?

By doing what you already know is right. You are only responsible for your own actions and when you generalize about a group even if you are a member, it's reverse racism and you are just as guilty as those racists who stereotype others and promote hate. Try to put things in perspective, the economy is bad and many states are in a formal state of emergency and or bankruptcy. People are too busy wondering how they will feed their kids or keep them off the streets to worry about what color your skin is. If you want to get grey hairs do it for a good reason over something that matters. We all ultimately share the same fate after all.
