How so? Why isn't the question 'Why is anyone being forced at all?' Their question assumes that someone has to be forced, which I fundamentally disagree with, so they should justify that assumption first.

Correct. They are equal, so I don't think either men or women should be forced.
It probably makes more sense to ban birth control at the same time men are required to die for the war machine as both would then be playing out their slavery-induced biological role in ensuring survival of the nation. That is if you're down with the whole slavery for war thing.
Fixed that for you.
When things get existential, the jobs favored by men multiply and the jobs favored by women decrease. And nowhere more than in countries and societies which are highly feminist and supportive of women, which seems counterintuitive but isn't.
