Im sorry you have a pessimistic view of "parental involvement."
im not a pessimist, or an optimist either. i would call myself a realist. in reality, such laws are merely bandaids.
You have 3 options, vote yes, vote no, dont vote.
the system is rigged, and untrustworthy.
So i'll just stay home and practice my latin because either way its "meaningless."
why not become a sidewalk councellor, or pray outside your local abortuary? there are plenty of effective means to shut down these places, and can involve other means besides direct participation. for instance, there are legal tactics (not to be confused with political), skillfull research teams, and other volunteers who provide assistance in their areas of specialty, which result in getting the mills shut down. politicians are not going to get their hands dirty; its not going to happen.
i invite you to listen to a talk given for sidewalk councellors in florida. http://www.ernestschaffer.com/swc
