 Pushing the rules beyond common sense   No offense to whoever moved the article to the current namespace, but it seems pretty arbitrary to me. Why not epicenicity? That would be much more general and accurate to what currently stands in the text. Epicenism suggests an ideology or movement. Indeed, the gender neutral movement could justly be called epicenism, only it isn't.  The thing is, if I remember rightly, the policy for nomenclature wasn't completely written in stone: nouns and in the singular is the rule, but it is honoured in the breach as well as in the observance in many articles. And so it must be. Here is a case in point.  However, epicene is sometimes used substantively (i.e. as a noun). It is analogous to dandy: first an adjective for finery, it became a nickname for those who adopted finery. Perhaps more tellingly, we have the adjective gay, now very widely used substantively with a different referent. Gays, as in gays and lesbians, is not an adjective any more. Lesbian is even more obviously an adjective, and just as obviously regularly used substantively.  If anyone cares, please return this article to a sensible namespace.
