It's funny how two people can see the same events and come to the exact opposite conclusion about what happened.
Some people wrote some articles about how "gamer" culture, which is/was mainly a badge used by mostly male hard core players, is somewhat outmoded now because most people playing games do so casually. Furthermore people calling themselves gamers and claiming to speak on behalf of their community created the whole GamerGate thing, an elaborate web of lies and false accusations with a few criminal threats thrown in for good measure. At the very least, the term has now been poisoned by those people and people who really love games as entertainment or an art form should probably more on to calling themselves something else.
Naturally the GamerGate people took this as a personal attack on themselves, which I suppose it kind of is. If you are one of those angry young guys who screams profanity into his microphone during every online match, or who doesn't feel like a "real man" unless he can virtually screw a prostitute and then murder her to recover his cash you may feel personally attacked when someone suggests those things are not positive aspects of gaming culture.
I've read those articles and they are clearly not an attack on all video game players. They are trying to say that the vast majority of players are nothing like the low lifes behind GamerGate, who are calling themselves real gamers. Language and labels change meaning, and although I enjoy games I wouldn't want to be identified as a "gamer" any more.
