No, I don't believe that. I am aware of deeper differences, but I don't believe these differences (at least on the macro) have a bearing on the ability to positively contribute towards the progression of the human race. Are you aware that your genetics are different from whoever lives accross the road from you, even if they appear similar to you? Of course... at least I hope so, Humans have been migrating for all of history.

I believe in meritocracy and cooperation. IQ (Even IF the correlation WAS causation in this above infographic, which as I highlighted previously, I don't believe) is not the sole indicator of an individuals ability to positively contribute to humanity.

I could never render an entire group of people as useless due to genetic differences. Nature is not everything, we must also consider nurture and the balance of the two.

Intelligence in itself does not equate good. It was Satans pride in his superiority over man which caused him to fall from heaven, iwhether you're religious or not the wisdom holds true. What you do with intelligence (high or low) and how you benefit your fellow humans defines your moral standing.
