That first link strikes me as not extremely scary, and it seems to be a rant rather than a threat which was sent to someone in particular. Furthermore, it doesn’t have specific details about injuries and degradation. It isn’t a photoshopped image of the person being threatened, either.
Gamergate is hopelessly weird—as you may know, the initial post was basically a man talking about having been emotionally abused by a woman, with only a minor mention of games and journalism, and it morphed into something completely different.
As far as I can tell, SJWs consider themselves to be part of feminism and/or the one true feminism. I haven’t seen a claim anywhere that they aren’t feminists, and at least one suggestion that there’s no point is saying that they aren’t feminists, even if they’re wrong-headed.
It wouldn’t surprise me if a lot of moderate feminists (like most people) aren’t engaging with SJs because that looks like a lot of work and no fun.
Is it just me or is this a proxy bravery debate? Are we collectively committed to getting to the bottom of who / which tribe is the true victim of those mean people on the internet? I’m not entirely sure why this has been promoted to the level of “have two extremely smart LW posters discuss”. You both are quite keen thinkers, and I imagine the topics this funges against for your attention will delight yourselves and the wider LW community even more.
