As I said before, with choices come responsibility. In this situation, given modern legalities, technologies, and social realities, the net balance of choices reside with the female. That's just the way it is. One hundred years ago say the balance of choices, and hence the balance of responsibility, resided mainly with the male. Now it's changed.
If men had a say in the reproductive choices of females then I'd agree that the male has more of a responsibility. But if it is up to the woman to decide if she wants to bear a child and she should accordingly take on the main responsibility.
This is why the most pro-abortion group in America is males under the age of 30 voting in their perceived short term interest of sex without responsibility. You can't build or maintain a decent civilization with that kind of thinking.
