Yuletide has hundreds of participants. Saying the M/M vs everything-else ratio is an example of fandom misogyny is not a personal attack any more than saying "this fandom is misogynistic" was a personal attack on LJ when the fandom itself may very well only be a few hundred people. It is fine to discuss bigotry manifesting itself in fandom trends, actually, and if you feel that is an attack on you specifically, I refer you again to the aphorism hit dogs holler.
