I support the legalization of cocaine but not other drugs, or because the cocaine generates too much money, that legalizing it could take a great resource for organized crime.
I also support the legalization of prostitution and gambling
I thought organized crime is considered a "bad" thing for the very reason they deal in illegal and immoral things like drugs, prostitution etc (apart from murder). If we legalize it, that ruins the whole point to fight it, it's as if we just declared them "legitimate businessmen". Also, I think morality is a very important thing, legalizing prostitution is just a surrender to the corruption of society, the often used "freedom" argument doesn't really justify it.
It's good though that at least nobody is for legalizing violent crimes like murder, because somebody might think that them staying illegal stands in the way of somebody's "freedom" too.
