Why punish the child for a dance that requires 2 people? You do realize there are many, MANY children born out of wedlock during relationships. And what about single mothers (and fathers) who are abandoned by the other parent? You speak with such a broad generality when in fact, you know that almost every circumstance is different.
You preach a pollyannish line, but it simply isn't reality- as sad as it is.
Simple solution: Don't have babies out of wedlock.
The only reason for state sponsored marriage is to make obligations legal.
Have babies out of wedlock, and don't come crying to the state to chase down your man (or men) for you.
For if the state is expected to enforce fatherhood whether or not the father married the woman, then what's the point of legal marriage? NONE.
Chase the fornicator's men for child support, and you undermine marriage.
Undermine marriage, and you undermine society and the health, safety, and future of all children.
Of course, the state is chasing unmarried men for child support, and so women are more likely to have children out of wedlock.
I say the state should put an end to this fiction of marriage, since it is no longer needed.
Everybody do what you want, and if there are consequences, the state will help you no matter.
