Where is he a proponent of "race science"? Citation needed.
And being an opponent of some of the more ludicrous off-shoots of modern feminism is not "alt-right", it's just common sense (and mainstream: for example only 9% of women in the UK consider themselves feminist[1]). And science, etc. Now I don't necessarily agree with his stances, but they are nothing if not well-reasoned and supported by data.
Yes, to me it is very clear from his words as well.
Anyway, since you are making the claim, it would be up to you to explain what in his words is "promoting" (what a proponent does) so-called "race-science".
First, you'd probably have to define what you mean with "race science".

Which is probably why he gets so much hate.
