Well I have changed myself, so let's start on the world.
I met a very newly 'born-again' Christian at the lake who shared with me how Jesus has healed him of all his anxieties. Poof. Gone. Of course I understood his zeal to promote his beliefs by claims of miraculous, instantaneous healing. The process of actual healing lacks in such a view. It takes time, I reassured him his journey was not over.
In other words, when we think we've arrived, it's only just the beginning. The world doesn't need fixing. We do. It begins inside and impacts others through demonstration, not through force.
The OP is no found to stop any person's choices. What the OP will do is initiate the conversations that are needed.
The conversations that are needed to moving us as a global society to ban alcohol for everyone? That's still taking away people's choice for themselves. It's imposing a belief upon them that they don't want for themselves.
Should we partake of alcohol when many suffer from its use, are we indirectly responsible by not taking a stance against the supply of a substance that we know destroyers people lives and families?
We have plenty of programs and education to let people know the dangers of alcohol abuse. There are laws that make the abuse of it illegal in many instances, such as driving, drunk and disorderly charges, and so forth. There is public awareness being offered, and more education is always a good idea to keep the public aware of the risks and dangers, warning labels, and such.
I see taking a stand to promote moderation the correct choice. Prohibition laws do not work, and they only make the problems worse. Heal the society that caused drug abuse, not blame the substance itself! That's what needs to be fixed. Fund better education standards, pass laws that raise the living wage, do things to help people
not want to abuse the drug in the first place.
You're not looking at the true enemy here. You're blaming the substance, not the root causes behind
why we might abuse it.
