There are a ton of different forms of human slavery in the world's history you can talk about without talking about the US and the Ku Klux Klan's connection to it. Probably not the best comparison.
It's a fine comparison given the point its responding to.
If someone brings up in the Klan in a thread about racism, do you think it would be constructive to tell them not to do that because it's just giving the Klan attention? That if you want to tackle racism best not to mention the Klan at all?
Because that's basically the advice being given there for GamerGate.
Look, it should be painfully clear by now, they aren't a group of trolls, and they aren't doing it solely for attention.
It's an organized group of misogynists and psychopaths who are harassing, stalking and swatting people as part of some crazy culture war.
I'm almost tempted to say it doesn't really matter how everybody else reacts to them. In the past, they've simply shown they'll make shit up out of thin air to rally their troops (it's kind of where the entire movement came from; a review that never existed).
Telling people not to talk about them or what they're doing gives them the sort of cover to keep making people miserable, and those people then largely have to suffer in silence.
