Everything legal has no social stigma?
Anyone who advocates "medical" marijuana is either knowingly or unknowingly carrying the water of hardcore leftists who want to destroy America.
Legal alcohol hasn't destroyed America - legalizing the less addictive drug marijuana won't either.
Of course it will. Why do you think that the overwhelming number of leftists are all for drug legalization? Because they're patriots? Because they believe in the 10th amendment? Or because they know it's destructive to American society and culture?
