This time, the secret is about female fanservice. monpetitpetaq claims that no matter how well-rounded and awesome the female characters in Bleach are, their awesomeness is negated by their large breasts because female fanservice harms real life women somehow. (Well, I can see the huge boobs being a problem for one's back...)
Anon tries to argue that both forms of sexism are equally bad, but monpetitpetaq and paperclipchains aint buying it.
Also apparently female fanservice is "icky" but male fanservice is ZOMG YUMMY!!!! And panzer_knight adds to the "big boobs = sucky character" pile. Huh, maybe it's just me but I can't remember the episode or manga chapter where Rukia, Tatsuki and Soifon had huge knockers spilling out of their swimsuits. XD
