Well, I know two males that went through this.
I had a good friend back in high school. I remember one day, he came to school, saying his parents were up late last night, fighting. I tried asking him about it, but he didn't go into it. I come to find out through the grape-vine, that his mom had cheated on his father, told his father that the baby (him) wasn't his, and the dad just filed and left. Never said anything to the family, or sent any money. And who can blame him?
Sadly, I haven't seen my friend in years. His mother couldn't support him (she was a stay-at-home mom), and he had to move. I think he joined the army, and disowned his mother. I remember how angry he was. He hates his mother, and doesn't know his father, and the father he thought was his isn't.
So this testing doesn't just affect the father. It affects the child. Because a man he had come to know as his father for 16 years, suddenly after one night, is no longer "Daddy," but a stranger.
Another guy I knew in college, moved out to California. I found him on facebook, and I saw he became quite the player.
Well, 3 years later, he gets hit with 3 years of child support plus interest from this woman. He was surprised, and went to court about it. Come to find out, this women never made any attempt to find him, and it never had to proved that he was served the papers so he knew he was the daddy. So she had the papers to tell him that he was a daddy sent to the bar he met her at. Never sent to his home address. Interestingly, I found out the only lawsuit that they don't have to prove they served you papers in California is for child support.
Well, he did a paternity test, and come to find out, IT AIN'T HIS! But guess what! He still has to PAY! Because he didn't do it in the time limit (one year after birth, until that kid hits 18) and California doesn't care. So he is paying child support, on a kid, that is not his, for some women that he hasn't seen in years to parent a kid. And he has no idea on how she spends that money. It could be spent on food and clothing for the kid, or beer and designer clothes for mommy.
So who thinks that is right?
