It isn't racist, it's realistic.
That category of things that we call racist does not exclude things simply because they are realistic. Political correctness isn't about being fair.
I would actually call a statement racist if it's primarily justified by racism (in which case it will be realistic only if it happens to be so accidentally). Since "racist" has a lot of negative connotations, it isn't useful to call something racist if you plan to agree with it, and therefore if I had to make a racially-based realistic statement, I'd call it something dumb like a racially-based realistic statement.
Every month on the month, Less Wrong has a thread where we post Deep Wisdom from the Masters. I saw that nobody did this yet for December for some reason, so I figured I could do it myself.
