Three cheers to Don. The latest few generations in this country have intentionally been taught to misunderstand the difference between "illegal" and "criminalized." In essence, even in the early 1800s very little was illegal, whether it be drugs, alcohol, firearms or even explosives. Over the years politicians gradually criminalized many of these things. The reversal of those actions ("laws) is "decriminalization," not "legalization."
Sound trivial? It is not. I spend a lot of time practicing this wording with my children and theirs.
