So, do you know accept that there is a biological difference between men and women? It seems that you do. But now you claim that we have to "beat biology" to eliminate the differences. Bravo! You are twisting and turning, pulling random arguments out of your hat as you see fit. What is your background? I would be more than surprised if it was technical.
What about this angle: given that men are apparently quite superior to women when it comes to abstract thinking, then why don't we do our best to improve male performance even more? By the time women will have caught up (if ever), we've probably lost a few centuries of progress. This concept is called "opportunity costs." I am not sure it's taught in Gender Studies.
Note that I'm playing devil's advocate to make you realize how incredibly shady your argument is.
