>> You keep stating that it's less invasive but I don't think that's the case. Come on - which do you think is going to work better - give a child a vaccine to prevent cancer (or smallpox or any of the zillion things wiped out by vaccines) or to criminalize cigarettes?
Exactly. It's more successful/more acceptable to jab a kid or force a bishop to offer contraception against his beliefs than to control a poison. The same people fiercely defending their own right to access poison, often are equally fierce in denying others the right to live by their beliefs or insisting that kids should be jabbed whether mom likes it or not. Do as I say, not as I do?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
