:::::::::::::The same expertise that the rest of the press has used, which is none. No one has undertaken or demonstrated a complete attempt to quantify the population of the GG movement at all, certainly not to the point that they can factually state anything (whether this is do to the unwillingness to do so, or the difficulty in doing so, we don't know). It is perceived as male dominated from several factors (the misogynyistic nature of harassment, that the tactics are those associated with a male-dominated culture, that this is a reaction towards an increasing diversity of the gamer population that puts the traditional gamer male at a minority), and certainly this is a logical conclusion, but still remains a supposition with no factual evidence to back it up. Young's point, which is just as valid as every other reporters' point which is using what can be visible gleened from the public forums, is that she feels the population of females is more than what "male-dominated" implies. This point is completely appropriate to include as a counterpoint.  (t)
