If race doesn't exist, does that mean that we must abolish affirmative action?

Race does exist, people just aren't supposed to be judged because of it. People just need to accept the fact that people are different, not eliminate what makes us different so that we will all be the same. I have a different race than some people, you should be proud of your differences. Differences are all equal, and that is what many people don't understand. It's like four quarters and a paper dollar bill. They are different, but equal. People have different races, but are all equal.
