Unsubstantiated and probably misguided, yes. Racist, probably not. Insensitive - probably.

What? Where?

The least I could think of myself as a racist.

UPDATE: I think I see your point. We have many interesting genes, myself included, none of them defines us as a person. I think it's irrelevant.

But in my comment I expressed a connection between a population statistical gene expression and a particular family. That is a tiny bit racist, agree. :(
