Hi buddy ;)
Such laws already exist as penalty enhancements in several states when people are found to be speeding or DUI. A similar mindset is penalties for children who are not in car seats, etc.
Do you want to play the game the other way? What is now illegal that you want to legalize regarding child abuse? The line for distinctions is not 100% clear. Hell - I think that day care is child abuse. But legal enforcement comes down to the art of the practical and what can be made a consensus and doesn't overly burden individual rights. Asking some dumbass not to puff a cancer stick in a closed car with a minor is not too much.
What do you do for fun, tear wings of baby moths?
Have you ever envisioned what your life would be if "for the children" didn't exist?
Would it have been as dreary as you fear?
If only those bastards had chosen you in that pickup game of ball, it all might have been so different.
Now's your chance, isn't it?
