Never in the real world, but I see plenty online. I think the ability to hide behind a keyboard and spew hate is something very specific to the internet. Plus, I don't go looking for racism, it's just not part of my agenda.
Let's not kid ourselves--racism exists, and will continue to exist, as long as the earth continues to revolve around the sun. The best way to deal with it is to acknowledge it, try to alleviate it, and refuse to allow it to control your life.
