Having said that, as a feminist I believe choice outweighs everything, and especially if it's a true choice, not to feed a drug habit or feed kids, that is their choice. I could hardly say I support women to freely choose their own paths and make their own decisions about their lives and bodies, but then put a qualifier where the sex industry doesn't count.
Do I think it's shameful - no. Do I want it for my daughter for the above reasons - no. There is a difference between it being shameful and less desirable as a career/money maker.
