Conor Freidersdorf helps us out. You either see legalizing drugs as Sean Hannity: you become complicit in drug use and abuse. Or you see the following by keeping drugs illegal:
The impoverishment of farmers in Colombia and Afghanistan, drug cartels undermining democracy in multiple South and Central American countries, tens of thousands dead in Mexico, violent drug gangs on the streets of America, millions of non-violent offenders in US prisons — these are just some of the actual consequences of the black market in narcotics, and if prohibitionists actually confronted the moral destruction caused by their policies, they wouldn’t need Gary Johnson, the Global Commission on Drug Policy, or anyone else to persuade them that by defending the status quo they do harm.
Gary Johnson’s comments on the Hannity show are helpful in this conversation.
