People seem to forget, in their rush to make bullshit arguments about how a female-only clan is sexist, that online gaming is largely male dominated, much like many many other aspects of society. If it wasn't, and there had always been a safe place for females to play without fear of being harrassed because of and about their gender, then arguments of that nature might actually hold water. A marginalized group seeking refuge amongst itself and excluding others to ensure that refuge is not any kind of "ism" because it simply would not occur if that group was not marginalized in the first place.
