There was a time when the idea of black slaves being real men (much less being free men) wasn't realistic. There was a time when women's suffrage wasn't realistic. Hell, there was a time when the idea of space travel wasn't realistic.
What the hell are you trying to prove? Instead of worrying about what's "realistic," why don't you try focusing on what's possible.
Black slavery against drug addicts ?
womans rights against drug addicts ?
Space travel against drug addicts ? (amusing connection aside)
what am I trying to prove ? what are you trying to prove ? Why would I want to focus on a way to make being a drug addict perfectly acceptable ?
I would rather focus on possible ways to stop the explotation of labor forces that would improve inner city and other local environments and promoted a real productive work effort... that was worth the effort.
