One parent per household. Historically, that has been women. By their nature, women are superior child-rearers, not least of all due to the simple anatomy of how breast feeding works.
I believe in evolution and it needs to get taught. I believe in science, not mythology- you are entitled to your own opinions, not your own facts.
Men and women are perfectly equal with regard to raising children. Religious people may think that women were created to be mothers, but science tells us clearly that millions of years of evolution prepared men and women for fulfilling desk jobs in office buildings. Himan females are biologically identical to men in every meaningful way, and none of the very few distinctions have any connection with their culturally/religiously-imposed roles as primary caretakers. As stated above, we all have nipples.
Why would natural selection have paired up men and women to have complimentary roles in raising offspring? It doesn't even make sense. What advantage could their be to one body being designed to rear children, and another to do things like defend the group or hunt? What a jumbled mythological mess!
So if you believe in science, you have to believe that 20th century feminism is a perfect reflection of nature. It's not that complicated and perfectly consistent.
