I agree we cannot make pregnancy "fair", for obvious biological reasons.

But we could make the situation when a women is pregnant more egalitarian for both parties. IMO your satire is not helping towards this goal; it just ridicules the male position.

> "Men will never risk their lives to give birth."

True. But it's also true that men sometimes risk their lives to protect the mothers and the children - and they always have.

Male sacrifices are somehow different from female sacrifices, but they are no less. Something most feminist choose to ignore.

> "That's why the satire works."

Your satire might works for self-centered women for whom "It's all about the woman" and like to bash men.

It isn't working for men; you're not getting any male to join your cause this way. :-/
