I don't find that article very persuasive in that she's making blanket assertions about large groups of people. Do "we" really consider sex sacred? I don't.
I believe that the article does describe that woman's experience.
I don't believe that article describes the experience of every sex worker.
We should work towards a society where people are able to choose to do work that doesn't impact them negatively.
If we were to make make the creation of porn illegal, we would cause more abuse, exploitation and shaming of porn stars.
Here's an op-Ed from someone with direct experience.
