What I Want To Know

As it is stated in my first post, I want to know mainly why Prostitution is portrayed so negitively in todays society in America. I plan to learn this by reasearching the answers to two questions. First: what aspect of prostitution makes it illegal? And second: why are most people, states, and politicians against prostitution. I hope to get information on both sides of the issue; for prostitution and against it, even though I am for it, so I may get a better, more well-rounded view of this topic.
