Someone claiming to be a racist, but saying they are not prejudiced. What do you think?

So this is a little odd thing, on a friends status, someone ended up admitting that they are racist, but are strong set to let everyone know that they are not prejudiced.

I just don’t see how that works. It seems that being a racist pretty much means you are prejudiced against that group of people, no?

I’m curious to hear your thoughts on this. Honestly, considering this person is a racist, I’m pretty sure they don’t have the best reasoning skills.
