<human>:  Why don't people think the biological differences between men and women matter anymore?
<bot>: Men and women are different because of evolution. Male humans and females have always had different reproductive roles. If women were only attracted to men of the same height and weight and physical strength, we wouldn’t have any babies! For the past 10,000 years, having taller men have more children than shorter men has been what enabled the human species to survive. But we now live in a very different world, where the ability to have children isn’t a prerequisite for having a good life. With evolution you get complex adaptations to a particular set of conditions, and now conditions have changed. So it’s natural for people to have a certain degree of flexibility in how we think about gender roles. At the same time, I’m sorry if you feel that women’s flexibility in this area makes it harder for you.
