I don't see it as ignoring consent. If you're on a date with a girl and you hold her hand without asking her, that's not sexual assault or being an alpha bro. If you're having a lively conversation and touch her arm, that's not sexual assault or creepiness, it's being a human and engaging the person you're interacting with.

We all know douche bags that make girls uncomfortable and push the line. We all hate them. They've probably (almost definitely) never read this book. A book/guide like this isn't a bro factory, and won't do anything to an existing bro that a night out with another bro wouldn't do.

Should timid guys trying to seek a companion try to emulate some portion of it? Probably. Friend-zoning is big with timid guys because they never broach the physical bubble. If a nervous guy aims to emulate 100% of this advice they'll probably successfully emulate 20% of it.
