The fact is, victimless is as easy to define as violence is or easy enough to have a pretty clear line.
Consuming drugs hurts no one but the consumer. Having 5 wives hurts no one as long as they all consented. Gambling your own money should be your choice.
While there may be the occasional things on the margin, most are quite clearly victimless.
>drugs hurt no one else
what about the family of the abuser? should a child grow up in the home of a heroin addict? doesn't society have the responsibility to protect children?
>gambling
humans are just dumb monkeys. we have psychological weaknesses to stuff like gambling. how many fathers will gamble away their grocery money?
>5 wives
is it really consent if a girl is too poor and uneducated to get a job and is forced into a polygamist marriage for subsistence?
Devil's advocate back at ya.
Drugs are only violent if they are illegal, rape is violence, gambling is sometimes legal-- noone should ever be locked up for gambling -- it is not violent. Morals should not be used, civil rights and not affecting others rights should be the metric. You start involving morals, a bunch of religions have different ideas of that. Violence and invading others personal rights is easy to define. The reason why we have a black market problem is defining things on 'morals'.
