Well, this calculus of protected classes they seem to be using does give off an impression that it was either designed by someone aggressively unthinking or sufficiently opposed to the premise that they tried to sabotage it as much as they could get away with. Under some pretty reasonable assumptions (complements of protected classes are protected; two permissible posts bolted together are a permissible posts), a system where protected ∩ unprotected is unprotected is trivially circumventable: for instance, rather than posting "women suck", you can always post "women drivers suck; also, women non-drivers suck".
