You're mistaken if you think that decentralized movements cannot be trivially co-opted. By their very nature, they are controlled by those who speak the loudest and command the largest audience.
So I must ask, who on your side of the #GamerGate hashtag speaks louder and and commands more followers than Adam Baldwin?
If you do not possess the social capital to overpower the voices of unabashed harassers, then your continued association with the hashtag only damages your cause.
(Note that I speak as someone who once worked in games "journalism" and is completely fed up with how shitty it is (not that the games industry at large is really giving me much to hope for).)
