Wrap it up for chrisakes!

So apparently there is a case in Georgia where the man is fighting not to pay child support. His argument, while they were involved, he explicitly told the woman that he was having sex with that he did not want to have kids. Apparently she was on birth control, him nothing. When she got pregnant and decided to have the child, his name is on the birth certificate, making him responsible for child support. He's taking it to court.
I had an interesting short debate with a male student in my class, because basically I said, he should have wrapped it up! (you know, taken some of the responsibility along with the enjoyment!) And the male student spewed that even had she been on birth control and the guy had wrapped it up, that somehow left 4 times in one thousand that pregnancy could still occur. I simply shook my head and wondered off. He really put some thought into that didn't he? My point is, accept responsibility, don't force it on someone else. He was, after all, having sex was he not? That is the primary function for it, in spite of the fact that many people also DO NOT WANT TO GET PREGNANT! How about him getting himself snipped in order to make sure that it doesn't happen. After all that surgery is reversible!
GEESH!
