I am a categorical opponent of the idea of legalization of drugs. As for prostitution it is a relic of the past. I have nothing bad in it do not see. Perhaps States who are against this go on about religious leaders.
And the transmission of all sorts of different diseases? This is not only immoral, but also a huge risk of getting a fatal disease. I think you would not want your children to work as prostitutes.
It's their choice and it's not for you or anyone else to decide for them. If that's what they like doing and they can take the risk...
I wouldn't want my children to work like that, but I would do anything to help them so that they will never have to. I also wouldn't like the government to interfere, it's not their family but mine and it's not their responsibility but mine.
I believe that drugs are a very big evil, because it not only destroys a person, but the person himself is capable of great evil for the sake of these very drugs. Legalization of these substances gives rise to even more problems.
