The thing is, to dismiss these as shitposts is disingenuous. These are statements of anger from groups that are routinely targeted by a sizeable portion of gamers. This isn't the same as someone posting "Fuck Blizzard and their anti-consumer bullshit" in a D:I thread. One is an angry comment coming from someone belonging to a group that get harassed, doxxed, and just tortured by the internet, and the other is coming from a gamer that is facing, at best, mild inconvenience by having a game they can't play. There's a massive gulf between the two. What really happens to men as a result of the off-hand comment? A hurt feeling? A sense of anger that'll fade away in an hour at most? It hurts being targeted and misgeneralized as something hurting the hobby you love, right?
Now imagine that feeling, but its amplified by a thousand and its constant. That's how I imagine the average female gamer feels on the internet. Speak up at how you think its nonsense that a courageous hero is wearing a chainmail bikini and high heels? Hate. Speak up about how you find Japan's fetishization of minors off-putting? Hate. Imagine being called an SJW and an immense amount of slurs, all because something made you feel hurt and a bit angry and you spoke up against it. That's what these folks are feeling now, and that's what women and minorities feel on a near constant basis just for liking games and wanting to be better.
