Just watch little children play, girls and boys. They play differently, from early childhood on. And they are interested in different things, from early childhood on. The different playing styles and playing interests correspond with the different roles men and women played over the past several tens of thousands of years. And political ideologists claim that this has not left traces in our genetic code, and can be ignored and denied or treated and manipulated from one century to the next!?
