Those typical white voters are just racists.
It's bred into us, after all.
That does raise another question, though. If white racism really is bred into us like Obama says and there is a racist gene, it must be a genetic disease and disability and should be protected under the Americans with Disabilities Act.
I can see it now. Employers having to provide reasonable accommodations for racists, having to provide separate but equal facilities because minorities make whitey feel uneasy.
