Downvoted: You seem rather confused in your thinking -- and you seem to be projecting some confusion to the rest of us as well. I don't think anyone here has confused the meanings of the sentence "Group A has lower average intelligence than Group B" and the sentence "All members of group A have lower intelligence than any member of Group B" -- that's a confusion which you spend the three first paragraphs needlessly disentangling for the rest of us.

As for your last two paragraph, you seem to be thinking that for Eliezer to mention one example of the universe's unfairness, means that he necessarily considers it the prime example of said unfairness. Hardly. It just came up, because another person mentioned differences in intelligence as a sign of an unjust God -- but they limited said thinking to only racial differences, not individual differences.
