Seems to me they've been pushing a return to Constitutional powers for the Federal Government. The drug prohibition is one of the most blatant usurpations of power and one which defines the essence of the battle so clearly.
Many see the issue, I'm one, as plainly a violation of individual rights protected by several articles in the Bill of Rights. Others with whom we often agree on other topics feel we're not entitled to behave as we wish even though we do not violate the rights of others.
Specifically, if I become violent and assault you or others, or steal from you or others, I should be locked up so I can't do that, regardless of whatever substances I've ingested prior to my actions against you. That you believe I'm incapable of refraining from violating rights or from polluting myself into doing so is an affront to me and my abilities to comport myself without such violations. It asserts your control over me as if a babysitter. I don't need that. It makes me angry, as it does many others. Society is not strengthened when adults are treated as children.
If we switched out rape, theft and fraud for illegal drug use the evil might kind of be more obvious to you, but for some reason drug addiction and ilegal drug consumption doesn't flash the EVIL sign for many here. The disease, death, violence and abuse of family and children associated with illegal drug use just fails to hit a moral tone for some here. Evil is still Evil no matter why you want to claim you want to do Evil.
Happy New Year to you as well!
