Not trying to be an arse here, but this article is pretty much a political pamflet that has little to do with your point, I think
(maybe it was a political point?).
In any case, you ended your preface with the line that you hope this website will tear down existing taboo's about interracial relationships and racism. Please bear with me, try not to knee jerk but...
Among humans a race means a group of people from a geographical region. You can call it anything you want (some prefer ethnicity) but these groups exist ans they are not "all the same". This does not imply superiority. That is just what lefists shout at people doing actual science. Who claims this today but a handful of supremacists that nobody takes serious?
It's a leftist trope that seems impossible to refute without being labelled a racist - which is dangerous I think. These groups have evolved differently - Why on earth would they not, given the completely different circumstances they evolved in. They have different biological traits (a doctor will never claim we are all the same for this very reason, or people would die!).
The jury is still out on the nature vs nurture question. But there is a hereditary component to it. But you can reliably predict certain parameters when you have enough data of an ethnic group in twin studies for instance. We do not use this knowledge. No, even worse. A Nobel laureate in biology had to sell his medal because he was fired and ostracised for suggesting we should use mean IQ data to help developing countries.
That is why I react with this rant. We can all ignore it in fear of being called a racist. But I despise this trend. It's the pinnacle of the bigotry of low expectations. Oh if we acknowledge a lower mean IQ in group A we will be called a racist so we just ignore the data and pretend everything that works in higher IQ populations will work in lower IQ populations. If we really want to help people in developing nations (and increase the mean IQ while at it!) we should stop being afraid of being called a racist and face the facts.
A pre-emptive disclaimer: No I do not judge people on the colour of their skin. I am a white person and my race is performing below east asians ashkenazi jews.I do not claim superiority and condemn any type of racial discrimination.
