The idea of a supprt group doesn't sound too bad to me, but the FIRST thing that would need to happen is that the father-to-be get a wake up call (i.e. a swift kick in the nuts... metaphorically speaking, of course).
This proposed support system would have to first make sure the father had the maturity and discipline to be a fathter, and if he didn't, then it would need to be equipped to help shape him into one.
As far as teenage pregnancy, I'll never agree that it is entirely the male's fault. It's 50/50 anyway you slice it (assuming both are teenagers... in the case of some letcher taking advantage, that's another situation).
Anyway, our legal system is supposed to operate on a "case by case" basis. If the father can demonstrate a true, legitamate intention to take proper care of the mother and his child, then I see no reason to lock him up (provided he actually follows through).
In fact, the threat of retro-active jail time for NOT taking proper care of your baby and his/her teenage mom might actually help the problem.
Obviously, I'm a grown man now, but I was raised with my sisters by a single mom, who worked two and three jobs at a time to provide for us. My dad was a dead beat, and my mother was always hoping that there was a man out there that would treat her, and us right. She had two serious relationships while I was growing up, but neither worked out.
In anycase, I had to learn a lot of lessons about being a "man" (as opposed to a male human being) quite late in life (figuring things out as I go along, basically). There are just some things that a woman cannot teach her son.
Sending a WILLING father to jail is a virtual guarantee that the mother and child will go through something like that.
If it were my son who got a girl pregnant, I would start off with the aforementioned swift kick in the nuts, and then I'd take him out, buy him some dressy clothes, hand him a shiny new pen and drop him off downtown and say: "I'll be back in six hours. You better have no less than 10 job applications filled out by then."
If it were my daughter who got pregnant, I'd find her boyfriend, and pretty much do the same thing, and I'd tell her that she needs to start working (she's only got nine months to make something happen) to save up as much money as possible.
Whether it was my son or daughter, if I saw that they were committed to this child and the other parent (at least as far as agreeing to raise the child), then I'd match whatever they'd saved up.
If they were slacking off, I'd take them both to court and have a custody battle for the child (hopefully before the child is born, it can be resolved).
Best post yet.
