I would guess that people buying a seduction guide don't really understand 'women' - in that they believe that women are somehow different, unapproachable and alien to them. The misogyny stems from the book not teaching these people that women are equal and worthy of respect, but instead teaching them to ignore consent and be an 'alpha bro' stereotype.
To me, that sounds like 'generalisations about women aren't disrespectful to women' - maybe it's a cultural thing or just the social circles I hang around with but I find it sexist.
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.
I guess my problem with it is if you're writing a book to educate nervous, timid, perhaps less experienced guys about interactions with people you're attracted to, it'd be nice to educate them in a way that teaches respect and kindness, not objectification
