Earlier quoted context omitted.
I am male and expressed an opinion that prostitution should be legal. But I have no desire to ever actually use such a service personally. My opinion is based largely on the fact that there are plenty of women who want to do this, or particularly enjoy it, as well as the unfortunate cases of people who feel they have no other choice. In either of those cases, punishing the people who are in this industry is wrong.
Punishment is a legitimate disincentive. Are there going to be fewer prostitutes when it is safe and easy? If the field is inherently injurious to women, why should we incentivize women to become prostitutes in any way?
It sounds like you just have a problem with sex in general and protecting women is about as much a goal of yours as when politicians cry "think of the children"
