hello, negative rep for this one...
Why not? It would prove that you were able to properly raise a child and cut way down on the Jersey Shore/Jerry Springer idiots that are clearly breeding faster then the decent folk of this country. Go check out peopleofwalmart.com if you need some help.
Whats wrong with making sure someone is capable of raising a child? If it the forced B.C. your concerned about then if you get knocked-up mandatory per-natal care and the second that kid pops out its gone, and you have no claim to it.
Well how about this? Anyone who tries to force any of my kids (i don't have any yet) to take birth control will get a bullet lodged in their head? This is probably the most intrusive solution possible in my opinion. Unless of course you just want to go the route of Communist China.
