That does nothing at all to undermine the point. Why would you expect them to do better after centuries of being taught to obey and strict separation and major disadvantages that still last? Recently I watched a lecture exploring the long-term public health consequences of apartheid ion South Africa. The blacks had been deliberately - and I mean as conscious government policy laid down in papers - taught to live a dependent life, obey the authorities, not think for their own. So of course you get horrible results now that they are "free". You think that proves something about them? When people say "it's cultural" as if that means "it's genetic" - that "culture" also is the result of the policies and treatment they received over the centuries.
