Thank you for this, I think you handled this very well.
I am actually surprised this silly GamerGate is still a topic, and I can only shake my head about their lies about fighting conspiracies. It should be obvious to any thinking and feeling (!) human being that this is no way to behave. I would love to just ignore this whole thing, because it is really depressing... but as long as people are threatened it is important to write statements like this. Let's hope those kids will get bored soon and find other ways to deal with their aggression.
