I suppose it's not really a point worth arguing, but I would suggest that skeptics also question their own assumptions. (See my sig)
I could understand why some people might draw a line that includes doing cam work or having an onlyfans account, where the customers are at a safe remove, and maybe even being willing to meet some clients in a public place to go on a "date" but not feel safe going back to a hotel room to have sex. The former activities seem to be less risky.
Of course I could be wrong, but I see no reason not to stay agnostic on this point. You are so certain, but what do you really know? At least I know that I don't know.
