In that case, I would appreciate not referring to a trans-woman as "he". She's "she". End of story. Apart from anything, it's basic decency, regardless of what else they may have done. For the record, further to my stated interest in this part of the case, that designation could technically include me, though I prefer just "woman", "she" etc. In my experience, there's not many positive things to be said about people who won't accommodate that.
On topic, this sort of thing is likely to turn those of us who are on the fence away from what GamerGate claims to stand for, and sadly reinforces the (albeit rather hysterically over-stated, thus far) claims of misogyny. Let's not go there.
