I don't disagree that standard language is dynamic and a representation of culture (and those who control it).
However -- while I have heard plenty of suggestions for resolving the issue from college english professors, none of them have managed to convince the Central Board of Oppressive English to accept their proposal, and so we might just be stuck with non gender-neutral pronouns and awkward she/he constructions for the time being.
'They' might emerge as a ambiguously plural/singular gender-neutral pronoun, but in the meantime I won't berate anyone for sticking to the accepted standard.
