Consenting adults. Hm. That brings up another thought. Two people meet in a bar, hit it off, decide they'd like to share a bed, go to a home or apartment or hotel room or whatever, have sex, and no one is going to stop them. They're consenting adults, after all, yes? A person arranges to meet someone for sex, which is then paid for, and suddenly we have a crime. Why? As long as it's two consenting adults, not with someone forced into prostitution by human traffickers, it's still two consenting adults who agreed to have sex.
"Like McDonald's" "not a career", but obviously some folks do make a career out of it, like McDonald's. As long as they are not forced into it or cheating anyone, what is that to you? Or me? Or anyone else?
I understand why some people oppose prostitution. It's certainly not a career choice I would ever advise anyone to make, legal or not. At the same time, I believe a person owns his/her body, and therefore owns his/her time and effort. On those grounds I will oppose and condemn human trafficking, but on those same grounds I will also say prostitution, consensual prostitution that is, should be legal.
If I'm wrong, tell me why.
