Guess what? There's parents like that out there arleady

. Ever see those vids of parents giving their kids weed or chain smoking cigarettes? I've seen one or two where the parents gave them ecstasy. The kid seems to slightly enjoy himself even, besides his eyes shooting back and forth. Uncommon, but it happens, and in those situations the child doesn't have options to say no. I guess some would say the courts have to decide if the child is mature enough or not to make the decision for himself? Hm. Tricky.
I don't believe anyone claimed that parents and children never make the wrong decision. However if your proposal is that the Government is more likely to make the correct decision then I will have to disagree wholeheartedly.
