Ask him. I've been in more than one debate with him. He's not very interested in separate facts if they mess with his ideas us spectrum people are more Neanterthal than others. Example, test asks if you have red hair. If you do, the test sees that as a Neanderthal trait since they had red hair. Thing is, both their and human DNA is now mapped out, and it's different genes causing red hair in humans and Neanderthals.

Personally I'm very bothered by the thought of Africans as inferior and things like that.
