What's wrong or racist for being against affirmative action?

The United States has a black president. The U.S. government allow millions of people from Mexico & Central America to emigrate here illegally. And whites are expected to become less then 50% of the U.S. population within the next 40 years. So why should America continue to have diversity programs that give preferences to everyone who isn't white? a href="http://www2.timesdispatch.com/news/2010/jul/23/webbgat23-ar-348131/" rel="nofollow"http://www2.timesdispatch.com/news/2010/…/a
