I agree to a point:
Drug laws ARE racist...also they've been proved over the last 60 odd years to have caused MANY more problems than they have fixed. Unfortunately, white Christians seem to feel that legislating (their) morality is acceptable. Time has proven this idea to be wrong, but our government/"the powers that be" NEVER admits that a mistake was made by them. And so many Americans NEVER question authority...an inherently American right.
Being a strong believer in the Libertarian philosophy, I'm ABSOLUTELY against "victim-less crime" laws. We DO have the right to decide what is right for us, individually!...Although, our Government prefers we not exercise these rights.
On the other hand, if you know something you do is gonna get you incarcerated, and you know that you'll not get a fair trial, then don't do it...or don't get caught.
Yes, the "old ways" do work...if we are allowed to utilize them.
Ultimately, we are the master of our own ships.
