i'm not qualified to draw a line. these aren't degenerates until they are. same with junkies, alcoholics, sex addicts, etc. the state doesn't finance the programs, but these are still real conditions.
who said it's an excuse to anything?
that's the problem with addictions: you, a supposed non addict don't even realize that it's a condition, yet you'd expect someone with the condition to be aware of his actions. and they aren't. you're not the same person when you're addicted.
i do hope you'll never experience anything like that in person, neither as an addict, nor as a friend. you'd eat your words in a second.
