You can't go through life redefining things and expecting others not to challenge you. If you feel porn has a negative effect on some people, make your case. Don't do it with silly word tricks.
I'm sorry, but porn isn't prostitution. Prostitution is prostitution.
Sorry; I didn’t realize you were being reductionist and narrowly technical. I am not interested in the civil law definition of prostitution. I am interested in the moral content and the effects on the persons exposed. I see now that you are not.
