On the contrary, it's a sign of our "evolution" that sexist ideas like the one in your second paragraph are now increasingly subject to fierce rebuttal.
People being different should never be used as an brickbat to claim inferiority - all people are different, and equality is one of the most important values to be found.
Also, I'm pleased to see you didnt take downvotes either.
Calling something sexist and leaving it at that isn't a rebuttal, and the more people agree with something empty, the more they have to answer for, it doesn't give a gram of weight to the thing. But you're not wrong since evolution doesn't exclude regression.
Edit: to say that in the light of Aloha's response, I guess my post was a rebuttal. But not a refutation... Sorry, I'm just quibbling now.
