"I have never understood victimless crimes."
Me neither! As far as I'm concerned, if there's no victim, there's no crime.
Along those lines, I think drugs, gambling and prostitution should all be legalized. If people screw themselves over in their indulgence of any one of those, so be it. They should be free to do that. But they should also know that when they do, its nobody else's fault (or problem) but their's.
