I just think these men do this because they can. If they had to have the babies inside them, it's a whole different story, one they will never understand as they are not built that way. Women are programmed to nurture and care (well, hopefully most of us are!) so it's just the most alien, strangest, disgusting concept to do this to a vulnerable little baby. That is why we are so angry at them, it makes no human, biological sense. I reckon all of us would never leave our men if they were the ones who had to give birth.........hmmm, now there's a thought.
