If female fans are dismissed more easily, then so are their interests, their spaces, and their primary forms of engagement. Or, said differently, gender discrimination occurs on the level of the fan, the fan activity, and the fannish investment. There is a ready truism that enthusiasm for typically male fan objects, such as sports and even music, are generally accepted whereas female fan interests are much more readily mocked. Likewise, fangirls are mocked as is fan fiction, an activity more commonly ascribed to females. More than that, affect and forms of fannish investment get policed along gender lines, so that obsessively collecting comic books or speaking Klingon is more acceptable within and outside of fandom than creating fan vids or cosplaying. Even the same behavior gets read differently when women do it: sexualizing celebrities, for example, is accepted and expected among men but gets quickly read as inappropriate when done by women.
