I cannot understand how German men can be expected to fight while women are exempt. It's pure sexism against men and also very insulting to women. I'm opposed to conscription in general, but I live in Sweden with gender-neutral conscription laws, and I would do my best to defend my country if it became necessary. If I were a man in an alternate version of Sweden with male-only conscription, I would feel so disrespect…
Sure they can fight and kill.
But a country that loses its ability to make more people won't last longer than a generation.
Two things a country needs from which all other needs derive: people and a border that can be defended.
Men historically get sacrificed to protect the border. And women "sacrificed" to make more people.
Food, entertainment, religion, government, taxes, education, etc... it's all to serve those two fundamental requirements.
