Men and women have evolutionary roles, this is true no matter what differences you are confirming with my argument. You sure as hell know that I'm not saying 100% of evolutionary roles are essential and that's even more so with the welfare state. This has nothing to do with religion, men and women have evolutionary roles because they're scientifically better at certain things so you can cry me a river with your feelings. Anyways, as a father I know parents can be defensive with their kids because they want the best for them, but that's not an argument to cut boy dicks or hit children for discipline. That leads to the next topic, if someone suggested that a mother and father being together to raise their children is better then you'd be as defense as the parent's who spank their kids. Obviously it's not everyone, but parents who become separated generally wished things were different or worked out.
