Jesus, seems like an over reaction. Books and guides like this are nothing new, and should be taken in context/used appropriately. A nerd in a club is going to take this brash advice like:

"All the greatest seducers in history could not keep their hands off of women. They aggressively escalated physically with every woman they were flirting with. They began touching them immediately, kept great body language and eye contact, and were shameless in their physicality."

And not go up and rape a woman, but perhaps take a chance and put their hand on the girls shoulder during conversation to show interest, where they might have otherwise oddly looked away from them. Also, there's a huge difference between personal conduct in a night club and in a library.

Anyhow, I'm a nerd with a SO that has never drank and hates night clubs but that's my take. Seems like any other topic and people would be crying free speech and censorship. A guide like this isn't going to turn a normal man into a rapist.
