Pregnancy is the only thing that makes women useful in the eyes of a strictly patriarchal society. Now think men could suddenly give birth to children as well... it would probably become a completely new way for men to dominate the female gender.

Seriously. What the hell. You think alpha-male types would want to go through the pain and difficulty of having (and rearing) their own children? I thought the Patriarchy was all about keeping barefoot in the kitchen with the kids so the men could work and play golf.

(OP, I support your dream. I wish biology didn't stand in your way.)
