From what I've seen, there are strong feminist advocates on both sides of the issue. The article gives examples of both. One side insists that prostitution is inherently coercive and especially focuses on how often women in prostitution are exploited by pimps or others. The other side focuses on every person's right to do what they please with their body within the bounds of consent and on making sure women in prostitution can comfortably get healthcare and police protection. I don't think there's an easy answer to this question from a purely feminist perspective.
