Earlier quoted context omitted.
You're right, it's not a matter of opinion, and in this case you are the one with the wrong opinion.
99.9% of humanity is on my side on this. You're free to have your opinion just keep in mind it isn't valid just because you say it is. I told you how things are and you did not refute what I said, you just made ideological statements and mental gymnastics to help you hold on to your opinion. The world is not as black and white as you want it to be.
If 99.9% of humanity agrees that sex work is bad, then surely sex workers and their customers combined must make up at most 0.1% of the population, right? And yet there are an estimated 1 to 2 million prostitutes in the US, so about 0.2% of the population, and presumably the clients outnumber the sex workers... so your magic number seems very very unlikely. I doubt even 99.9% of your friends and family would share your opinion, though they may not feel comfortable admitting this to you (you seem rather judgemental and close-minded).
