I agree, at least when it comes to the "sin" crap. I am definitely a libertarian on that. I'm pagan, and one precept many of us honor is this: "If it harms none, do as you will." Sounds like a license to behave in a terribly immoral fashion, doesn't it? It really does, until you start to ponder that more fully. One example might be, since we're talking about Demon Weed here, the ethics of toking. I load a bowl and get mellow... not hurting anyone, right? In my current situation, that would be true (although you could argue that I'm harming myself physically since it makes me cough a LOT so unless we have company who want to get social, I refrain).
But if we flashed back 20 years ago when I was still working, had kids at home, it wasn't legal-it-was-a-felony.... would my innocent bowl maybe cause harm? Arrest? Smoke making my kids' lungs hurt? Random drug test, fail, lose job?
The reason we need to have so many laws about don't do this, don't do that, I think is because we're all kinda lazy and it's too hard to think ahead of the ramifications of our actions like in my what-if, above.
What do you think?
