But removing prohibition is a far cry from providing free heroin to addicts... I understand the argument about removing the black market, but after seeing San Francisco in person it's hard to agree that free drugs and paraphernalia makes things better overall.
If my friend became a heroin addict, out of care for him or her I would not provide them with heroin even if I could afford it. Why should I treat other fellow humans worse?
Why is it different when we're speaking at a societal level? Love for neighbors should increase, not invert, when the number of individuals concerned increases.
