Freedom of choice isn't as black and white as you seem to think. Rarely do women engage in prostitution voluntarily.

I'd be willing to bet that in nearly every case of prostitution today, both in this country and throughout the world, there's a tragic backstory -- child abuse, physical and/or emotional coercion, drug addiction, poverty, kidnapping...

Besides, compassion isn't just for the blameless. It's for anybody who'll accept it.
