So...the man has no responsibility?
Do have any daughters, and have you had this conversation with them? Would you be as sanguine if one of them got pregnant and the father - or, in terms, teh sperm donor - fled the scene?
I've never been pregnant. Do you know why?
I learned at a young age how not to be, and expanded my knowledge base to make certain it didn't happen later in life. I highly recommend it.
Don't make excuses for women who are careless, stupid or lazy. It makes us both look bad.
If the man is not married, engaged, had not made a commitment to support the baby, had not used some form of force or fraud, no. And no parental rights. Going after the "deadbeat dad" in these cases isn't realistic, and doesn't recognize where the real responsibility is. If the women wants to get pregnant, no matter what the policy is toward men, she will do so. In these circumstances the male is just a discount sperm donor, no sperm bank or doctor's office involved. Hounding them for money just subsidizes the problem system (if it even pays for itself given the bureaucracy involved.)Again, if a woman wants to get pregnant, the choices of individual men are irrelevant. The public policy answer has to be to eliminate the incentive for women to irresponsibly have babies.
Where there was a marriage, or a support commitment upon which a woman relied, that is very different, and I would hold him responsible.
