This kind of law is new to me. It seems to me that if "encouraging a minor to disobey their parents" is illegal then a few state legilatures are guilty. Such as those states that make it legal for minors to get abortions without parental consent and allow their schools to pass out contraceptives without parental knowledge.
Perhaps Maine, California and other states with those laws have no "unlawful transaction" laws. IMO they should and state legilators should be charged and tried under them.
No child should be given contraceptives without parental apporoval. That is disgusting, IMHO.
It's too bad that private schools are so expensive. (Especially in homes where home-schooling is out of the question.)
Personally, I detest having my taxes go to support the public school system. Taxpayers should be able to choose where their tax dollars go.
