Let's see, a case of felonous fraud; a several clear cut cases where men are blackmailed (pay, or go to jail) into paying for children whom they did not father; and the poster has "one serious hangup"? Naturally, the problem is with the poster, not the law. < /sarcasm>
At first it was disheartening to think that there is such enthusiasm for denying a child who turns out, through no fault of his own, not to share the ersatz papa's DNA. Not that you can't make some moral argument for it, but it appears motivated chiefly as vindictiveness against the wayward female. Hurting the child probably wouldn't go far in hurting such a female, but the child remains hurt nonetheless.
If your eyes are blue, and hers are too, baby better have the blue ones.
