"I don't feel the need for us to be equal. If feel that the idea that we're not is often a cop out..."
If the evidence supports the conclusion, we must accept it regardless of our personal biases. My general claim is that each person has a range of capabilities that they are born with, and that this range is ~ normally distributed across the population. By definition these ranges do not overlap for all n. This is supported by both anecdotal, population data and experimental animal and human models to the best of my knowledge.
As for your second paragraph, well as you can see I never claimed to the contrary. I completely agree that one should find a method of learning to maximise their individual potential, and that the range of what is possible for an individual is quite large - see my claim above. In fact I am very close to someone working on this very topic - determining the optimal learning strategy for children to maximise their learning rate.
