Even if you're correct that her being abused in her childhood is related to her choice of career, what do you think you're adding to the conversation by bringing that up?

What are you actually trying to do here besides shame her for having been abused as a child? That's really the only takeaway from your comment here, that people shouldn't read her writing about prostitution as a business because she was abused as a child. That seems particularly nasty on your part, even if unintentional.
