We agree, men and women are different. That's what I said. However, it is not always the binary difference that XX and XY chromosomes might suggest. Part of the clue is that we all have an X chromosome.

When you say "very physically different" first, that is subjective and not quantitative and, second, it only applies to the average. If you were to pick a man at random I can probably find a woman who is just as tall, for instance.
