I haven't checked any specific article other than what has been presented here. Personally I think that racism being "genetic" isn't any more shocking than "rape" being genetic. We all agree these things can be overturned by education so it hardly makes up for anything other than a token win.
Unlike some conservatives I'm not obsessed with how humans are "by nature", some people will gladly refuse to accept natural homosexuality like hypocrites and argue that natural selfishness should keep us from giving universal income to people. This is not about nitpicking or choosing arguments to fit a narrative for me. If racism is somehow natural then it's a serious consideration to take in certain poor communities.
