That is a silly straw-man argument. Because someone you (or I) don't like says X doesn't necessarily mean that X is incorrect.
I'm sorry it offends you that intelligence is not equally distributed between different species or races of men. Some species are smarter than others. Think moneys and turtles. Some groups of humans are smarter than others.
That is simply how G-d made the world.
To be fair there other types of intelligence, thats just one.
Well regardless of color my family seems to do fine smarts wise,, and myself, guess I do not have a dog in this fight I guess.
Some people are more book smart, some people are more street smart, and things like wisdom, common sense, ethics are just as important as intelligence.
Just my two cents.
