This doesn't have much to do with atheism, but still.
I see a few pages back there was some bollocks about women wanting to be subservient, and 'innate' biology.
It's depressing that this is still believed, especially amongst seemingly intelligent people. The pseudo-science of most theories regarding evolutionary psychology seem to have become popularised, and it's really quite dangerous, and holds us back.
The fact is, women have always done a hell of a lot of providing, throughout history, and across many different cultures. Even today, women in Africa produce 70-90% of the food, they're the farmers, and they usually get the water for their families as well, walking many miles across blisteringly hot desert and carrying heavy loads. Before the industrial revolution of the 19th century, most men and women (we're talking the peasant majority, not the lords and ladies and knights) had very equitable roles in working and looking after the young - their (usually agricultural) work, as well as the domestic roles, would be shared. Couples were partners, and although they might have carried out different tasks around the home and regarding the young, they shared it. This makes sense. And this is seen across many different cultures, and also across the animal kingdom, where males and females have roles that intersect and change (female lions are perhaps the easiest example). You can also see this in many of the indigenous tribes that remain today in Africa and South America.
However, with the industrial revolution and invention of heavy industry, a lot of men started working in factories and many women - less capable of working in those heavy industries because of lesser strength - stayed at home. But even then a lot of poor women still had to go to work in the factories out of necessity and work as long as the men. They still got paid a lot less, of course.
As for 'innate' differences, read some Cordelia Fine, and Lise Eliot. They've debunked those theories, as well as the pop-psychology of the Men/Mars, Women/Venus. A lot of these differences that are supposedly 'wired' into the brain are actually the result of social conditioning. Our brains are very carefully attuned to the environment, and once gender stereotyping becomes salient, even subtly, it causes men and women to think differently. But this is culture, not biology (as I've described with the sharing of roles across nature). For a long time now, girls have been socialised into subservience. But when you remove gender stereotyping from the background, men and women's behaviour becomes remarkably similar in a lot of areas. With the reduction in the reliance of heavy industry across most of the developed world, most women work. They may take time out to look after young children (that's still a full-time job, btw, can we stop pretending it isn't?), but they almost always return to work, often because the family needs it. Dual-income families are the norm, especially after the recession. And this is the way it's always been, save for a few privileged women from the upper middle classes and upper classes who could afford to not work (a small minority). Women prove in education that they are equally capable as men, and the evidence is very clear that if there is good gender diversity of men and women at the top of most businesses and governments, performance improves.
And, far from all women wanting men to take the 'lead' (whatever that means) - couples that share work and domestic duties at least partially actually report greater happiness in their relationships than couples who don't; they're less stressed, and it's better for children.
Fine gives all this 'innate' nonsense a word - 'neurosexism'. When women were arguing for the vote and access to higher education at the end of the 19th century, the people that were denying it to them were not just using the Bible as a reason to deny them this, they were also using biology. There was a time when the brightest scientific minds in the world thought women were incapable of voting because they were too emotional, or that if they had access to higher education all the blood would rush from their ovaries to their brains and they'd become infertile. I'm not even joking. This is just an extension of that, as is most evolutionary psychology, which largely fails as a science because most of their assumptions are untestable, and infallible. And yet they're repeated in the media, spun out of control and used to justify basically treating women as second-class citizens, even amongst otherwise seemingly intelligent people.
