when I was in Rio, my US-acceptable "passivity" relative to the culture norm in Rio, got me absolutely no where there. It was only when I forced myself to be physically assertive that women started responding well and flirting back and I started getting datesThis ability to read feedback and adapt to a cultural context is exactly what the guide should teach. I know you say you're not defending the Kickstarter, but you're criticizing criticism of it, so the exact content of what we're talking about is very relevant. If you take a look at what the guide says, you'll know this has nothing to do with an "echo chamber" and has everything to do with sexual assault.
Consider the audience of seduction guides. They wouldn't be reading explicit guidance on how to verbally and physically interact with women if they had any understanding of the boundaries and expectations in their own culture. They should be learning how to read feedback from women and how to map out the boundaries in their culture and in each individual interaction with a woman. Instead, the guide advocates specific ways of physically handling women to people who are not remotely capable of figuring out whether those actions are appropriate in context or whether they constitute sexual assault.
Even worse, the guide teaches them that their "nice" impulses, their desire to respect women and their fear of making them angry by being openly sexual, are sabotaging them and making them less attractive to women. This is often true, but it's horribly irresponsible to teach people to interact in physically assertive ways while also teaching them to distrust their inhibitions against sexual aggression. If your inhibitions against sexual aggression prevent you from touching a woman while you talk to her, then your inhibitions need to be recalibrated. However, you absolutely cannot physically interact with women unless you have some trustworthy sense of how to avoid unacceptable behavior.
In other words, what the readers are in desperate need of is a way to figure out when they're making small or large mistakes, and when they're actually doing well. This would liberate them to start learning by trial and error. Instead, the guide actually says that men are notoriously bad at reading women, and you should never let any "signs" hold you back from the proper course of "ALWAYS BE ESCALATING!" What level of "resistance" is explicit enough to pay attention to? (Seriously, this is from a section titled "IMPORTANT NOTE ON RESISTANCE.") "If she says 'STOP,' or 'GET AWAY FROM ME,' or shoves you away, you know she is not interested." It then gives you a line to memorize -- seriously, a line to memorize for this situation -- and says, "If a woman isn't comfortable, take a break and try again later. All that matters is that you continue to try to escalate physically until she makes it genuinely clear that it's not happening."
Because "STOP" and "GET AWAY FROM ME" don't mean it's genuinely not happening -- they just mean you should try again later. Is this really good advice to give people who in all likelihood are already not that great at figuring out when they're assaulting somebody?
The kicker: "From now on you must ASSUME that she is attracted to you and wants to be ravished." Ravish means rape. It only sounds nicer because it is associated with an indistinct, rose-tinted past when rape could be considered classy under the right circumstances. (It is also used as a metaphor for overwhelming emotion, but the key to that image is the experience of being carried away against one's will, and once again the usage comes from a time when the concept of rape wasn't so intrinsically offensive as it is now.)
"GET AWAY FROM ME" means try again later, and you have to assume every woman wants to be "ravished" by you. This is not ambiguous material; this is material that teaches a model of interaction in which sexual assault is a commonplace side effect.
