That's exactly what they should have done, have some "booth guys" instead of just booth babes, just hire some hunks to dress as Kratos or whatever, then female visitors to E3 get some eye candy to ogle and get their picture taken with, male gamers wouldn't have cared and just found it amusing if you also kept the booth babes, it would have been fair and equal.
But third wave feminists like Anita were never interested in equality, they wanted gaming to become a female dominated hobby and culture, not something simply more welcoming or inclusive of female gamers, they wanted the hobby to shun it's original audience completely.
The only gate keeping that ever happened with games is stuff they started and now they deserve to be gate keeped and kicked out of our hobby.
