I think there is a general shift, and it is just as concerning as it is a relief. For boys are very problematic and wild and selfish, begin early to imitate the loutish swagger of their stupid fathers, while girls are generally sweet, caring, are given nice dresses, learn to be practical and helpful, brush their teeth and their nice silken hair to a sheen, etc. So, if they become preferred, unhappy boys will become more and more neglected and become miserable and sexually unattractive men. And maybe girls will change into demanding, selfish, hyperactive, loud, and brutal boy types?
