If the couple is having sex and has not talked about the possibility of being pregnent, then they are stupid and they should both pay for their stupidity, not just the woman.
I doubt you are a woman, since you'd know what ass holes most guys are but you wouldn't seem to mind if they were even more. There are enough guys that don't pay child support, why would you want to produce more?
And again, it's child support, for the child, not necessarily the mother. Your argument has no backbone.
