Maybe in happy magical fantasy land, but the real world tells a different story. It's full of men who want nothing to do with the kids they've concieved
And if you don't want said babies, you can abort them or give them up for adoption! You may be morally[/i] opposed to abortion, but that won't impact of the decisions of those who don't believe it is a problem.
The stuff of fantasy.
A world in which people always stop to think about whether they want children before they have sex, and people who automatically care for any and all children they concieve, may be a world you want, but it's not reality, and thus not relevant.
