Hypothetically suppose this poster walks up to your wife/sister and offers money to have sex? Would you say it was a victimless crime?
I believe it is a bad/evil person that solicits a prostitute.
I am more then 1000% sure that no one in my neighborhood wants a person like that living in the neighborhood.
Hmmm....if such a thing were to happen, I'd beat ten find shades of s--t out of this person, making HIM the victim. However, this person approached a prostitute, not a random woman going about her every day business. Again, here in NYC, there are hookers hanging out by seedy motels at all hours. It's very easy to differentiate them from "normal" women.
There's nothing bad and/or evil about having sex. If the only way a person can have sex is by paying for it, so be it.
