Females weren't brainwashed, they just dropped the mask and in reality they never liked men very much. Add to that is an environment that switches their hypergamy into hyperdrive with all the exposure to ever higher status men and being able to join the workforce. None of this was a conspiracy but in reality it was just animals reacting to the environment they found themselves in. Females are just severely maladapted to post-industrialism and they can't function for shit on a stick in it.
