Because the War on Drugs isn't about drugs; it's about control. The relevancy of "in a democracy, cheap legal dope and welfare" was unclear to me.
The people vote, and an ever growing number of drug addled, dependent, welfare voters supporting the left, serves the democrats wonderfully.
I see, that's almost another issue entirely. There is one thing that I believe is common to both: drugs are popular for two reasons [both escapism] -- #1) there is no justice, the evil prosper and are not restrained by law, while those striving to follow the law are are crushed by it; #2) a lack of real love in their life, I'm not talking physical or mere feelings, but a real you-matter God-reflecting love in their lives.
#2 is only addressable by the church, which in America is rather anemic (I know, I'm anemic in my walk with God); but #1, well nations are destroyed by God when they forsake justice like that... and who would want to live in such a world anyway?
The left says bring it on, more social workers, more welfare workers, more cops and government, and more lost souls to push the democrat button for free money.
And that makes it ok to push a system which is morally bankrupt? Which flies in the face of all previous American jurisprudance: assuming that all are guilty until proven innocent? (The ability to seize real property and monies before trial assumes guilt on the part of the accused which must gen be disproved.) A system that selectively enforces laws with vastly differing methods: the SWAT team for the "gangsta" in the hood, but a picture and naughty-gram [news-story] if they're a federal politician (Bill Clinton, Obama, etc)?
Good luck with all that.
