Why are these questions to ask oneself regarding prostitutes so one sided? Is the soul of a person ignorant of God's laws any less valuable to God? Who are you to judge who's ensnaring who?
Let me apply your question to another topic: "Why are these questions about stealing so one sided? Is the soul of a person ignorant of God's law any less valuable to God? Who are you to judge who's ensnaring who?" Your questions take on a different look if you agree that the topic being taught against is a sin.
You were looking at the questions from a book for boys about sexual issues. The questions are to drive home the message from the Scriptures that it is wrong for a boy to use the services of a prostitute. It was not written for a person engaging in selling their body for sexual acts. If you would like to see things from a woman's point of view, you can look at the girl's class book on the topic of Prostitutes.
Of course, the soul of a person is not valuable to you if you allow a person to sin without warning them that they are in sin. "When I say to the wicked, 'You shall surely die,' and you give him no warning, nor speak to warn the wicked from his wicked way, to save his life, that same wicked man shall die in his iniquity; but his blood I will require at your hand" (Ezekiel 3:18). You seem to prefer to pretend that a person is not in danger. I prefer to keep people out of sin.
So one last question: Who are you to judge a preacher about doing his job? "Speak these things, exhort, and rebuke with all authority. Let no one despise you" (Titus 2:15).
