Differences between men and women are down to the situation.

Sometimes the long situation. When a situation has lasted a long time, it sticks, and turns into culture, gender roles.

When a situation has lasted a really long time, it sticks hard, and becomes biology.

But most of the time, it's neither culture or biology which decides what men and women do. It's the immediate situation.

And even if you think it's culture, even if you think it's biology, if you don't like how men are (or how women are) you have to start with changing the immediate situation. The others will follow - eventually.
