Au contrare mon frair certified, prohibition is the antithesis of progressionism (new word?) now the democrats enacted the 1922 Harrison narcotics act as part of a racist platform, but I would not consider it progressive.
I am on the record as being in favor of the legalization of all drugs except 2, romazicon and narcan. If you OD and are not 6 yrs old or under or visually impaired, I mean accidental OD, then Darwin wins.
But to ascribe prohibition to liberal progressivism, well let's just say I am highly skeptical.
