Do you also respect rapists, child molesters and serial killers? They are people too, after all.
That is, as
Liar said earlier, an absurd non-sequitur.
As a humanist first principle, we owe all people a basic level of respect as fellow human beings.
Some people, however, squander their right to that respect by committing terrible crimes. These would include your rapists, child molesters, serial killers, ranch dressing enthusiasts, and so on.
The act of prostitution (personally providing sexual services to those who request & pay for them) does not, in itself, harm anyone. It simply responds to an expressed human need. In my view, it's a
good thing that actually
helps people -- or at least can.
Pretending the ordinary truism that "all people deserve basic respect" is an attempt to defend the likes of Larry Nasser and Ted Bundy, on the other hand, is simply asinine. I mean, come on. Even
you can do better.
