>> "Heroin can be used responsibly. Marijuana can derail lives." My view here would be both should be legal. Any of the negative effects to society of heroin use will already be covered under current law (theft for example). You can derail your own life if you want, as long as it doesn't effect society at large. >> "Areas where child porn is legal tend to have reduced rates of child abuse." You're forgetting that children were abused to create that content in the first place. And even if no more was ever created the physiological damage to the persons who know pictures of them are out there is undeniable. >> "if we ban everything we personally dislike or disagree with on a global scale, we never will find out." I think that was my point. We should not restrict things based on our personal morals. If it causes harm to society restrict it. If not, even if you disagree with it, allow it.
