Rather than curtailing women's right to vote, my preferred solution would be to increase men's right to not be conscripted.

As a German citizen, this’ll certainly make me thoroughly uninterested in the gender pay gap for the rest of my life.

No, it literally says the law says you must seek permission if you wanna leave for more than 3 months and the govt must always grant you this if not in a war. And if you fail to seek permission nothing happens. You can ignore it without consequence.

The obvious solution is to include women in draft rolls.
