Here is my logic. Intelligent women are molded that way through reading and studying, things that are mostly written by men.
Intelligent women are molded by their intelligence and experiences. Some of that experience comes from men, some come from women. If they are intelligent engineers, most of what they read was written by men. If they are intelligent poets, most of what they read was written by women.
Even if they read female authors, which is a smaller percent, even her exposure and references are mostly male.
That is your own bigotry showing through. Women really don't depend on men as much as you think they do.
Maternal instinct is different in that it was a woman's culture passed down from mother to daughter, with grandmother there to make contribute through the wisdom of experience and the past. This is something that is not male in origin, but rather used to be of women and by women. Men can study and read other males the same as women. The liberals made women feel that the uniqueness culture of women was second rate, and that somehow the boys have the better toys. Not all men have bought into this, since they prefer more exposure to the mysteries of women. When women dumb down this means they try to shift from male mimic into a purer female. Men like this because it is natural.
So you equate "women dumbing down" to "a purer female." That kind of misogyny gives a lot of insight into your other posts.
