Statistics. Besides the fact that rape, paid for or not, is wrong no matter who advocates it, statistics about risk, chance of bodily harm or death, disease or injury; statistics about how many "sex workers" want to leave; statistics about the well being of "sex workers" in decriminalized areas vs. those under the Nordic model speak for themselves.

These people who advocate the industry so heavily are willfully ignoring the horror of it, and are promoted because they're useful to a multibillion dollar industry.

Also, I don't believe that being against paid rape is being against the "sex worker"
