A long time ago, when I would still debate with the occasional feminist, I found a lot of their arguments began with the phrase
"If men got pregnant..."
They would use this to try to make points about abortion rights, child care, welfare and on and on. Every time I would hear that phrase, I would interupt as rudely as I could get away with:
THEY'D BE WOMEN!
Western women have imposed a whole culture of catering to the whims of women who are pregnant, have ever been pregnant or might be thinking about being pregnant someday. Their physical, emotional and especially financial needs are placed above everyone else's.
The women I have known from other parts of the world think American women are total wimps regarding pregnancy, childbirth and parenting.
When I was in the Army in the mid-80's, the married guys told me how their wives begged them to get them approval to have their children in a civilian hospital. This was no small thing for a junior enlisted guy to pull off; kind of like getting your health insurance to pay for cosmetic surgery or something. The reason the wives wanted this was that they wanted to be pampered and the army hospital didn't do pampering. The army nurses would roust the new mothers out of bed for exercises rather than scurry to their bedsides to fluff their pillows and offer them snacks. That is how a masculine organization handled childbirth.
If, by some bizarre science fiction, men started having babies while still being men, there would be a few changes and I doubt women would like them much.
