Particularly since the introduction of equal opportunities laws.
I'm glad, I take it you split everything 50-50.
An article I found.
"It is hardly absurd to think that the parent who gives birth may have a biological predisposition to be more attached to the baby. On the other hand, a biological predisposition is not a universal imperative.
Men thrust into a "Mr. Mom" role because they are out of work when the baby arrives often feel heartbroken when they have to walk out the door."
Obviously it isn't the case that every woman acts this way and every man acts another way, but it doesn't make any sense to simply rule out that biology is a factor.
"Gilligan contrasted women's "ethic of care," based on human needs and relationships, with "male" moral reasoning based on rights, justice, and abstract principles.
"Difference feminists" usually skirt the question of where the difference originates, though Gilligan dances on the edge of arguing that childbearing gives women "easier access...to the fact of human connection.""
"That men are more likely to think and act in some ways and women in others, and that every man or woman should be treated as an individual, are two ideas we ought to be able to hold at the same time. This means avoiding comments like, "Each sex seems to have a different definition of what constitutes success in life" (as Browne writes, quoting from a 1968 monograph by psychologists Joseph E. Garai and Amram Scheinfeld). Sexes don't have definitions of success; people do. But it also means accepting that in a nonsexist society, most corporate executives may be men and most "primary caregiver" parents may be women."
and, interestingly...
"Some scientists report pressure to stop or bowdlerize sex difference research. In John Stossel's 1995 ABC special, Boys and Girls Are Different, Bella Abzug and Gloria Steinem dismissed such research as "poppycock" and "anti-American crazy thinking.""
