Don't try to blow this off as some kind of SJWer bullshit. I believe those people actually exist, but I don't believe as many of the people you think are that are in fact that. I think gamergate is bullshit, and I have had passionate argument about how the name "feminist" is sexist and had to personally field the arguments about how it's not sexism if you're on the more oppressed side. Well, I could see how that could seem true if one doesn't own a dictionary... but let's face it, 1) the core claims of Gamergate have now been shown to be overblown at best, 2) there is no public evidence that any of the claims of harassment or threat at question were fabricated, only speculation, and 3) gaming journalism has long been corrupt, and even if all the initial claims were true, this would have been a minor example. So, being prepared to have a massive fight about it (even putting the discussion of threats and harassment aside for the moment) is fairly pathetic.
Do you really find it hard to believe that these death threats are genuine? I don't mean to imply that they are genuine in the sense that they will be acted upon, but that's not actually necessary for them to be an attack, is it? In fact, depending on where you live, it often is not. It's not okay to tell people that you're going to kill them if you could carry out the threat, because of the real psychological impact that has. We don't want a society of fight or flight. Being able to relax once in a while is, in fact, one of the primary goals of civilization.
