Polygon has an amazing piece on why gaming culture and young white male gamers are so toxic. They interviewed a number of folks doing actual academic research and professional journalism on the topic, and the answers are sadly exactly what you expect. Scared racist white guys have had a lot of time to fester in their little bubble, and are very resistant to any change that means they aren't always Übermenschen.
Excerpt via Polygon, but read the whole thing:
Why are gaming’s toxic men so enraged?
Women and people of color are beginning to appear in games as powerful characters with their own agency. Slowly, women and minorities are starting to hold senior positions in game development and game criticism. Why is representation — within and outside the art — so offensive to gaming’s toxic men?
Soraya Chemaly:
There’s a lot of sociological research about hierarchy and status in the gaming space, and the misogyny and aggression that comes out of that.
We know that the dynamics of women’s visibility online, particularly in what are perceived as competitive situations, can often result in lower-status men feeling threatened, and then dogpiling on women who have more prominence, status and visibility.
We see that in gaming, and we see it in the same way on Twitter where they have a two-tiered verification system that makes women extremely visible in prominent ways.

The mythos of heroic, powerful men who are in charge — who are respected, successful and dominant — is a narrative that is really changing. The status quo in video games is adapting, which feels threatening to white, conservative men, even younger ones.
It can be hard if you’re in the position of privilege to feel like something is being taken away from you. To fail to see that this is really about stopping other people being ignored or abused. I don’t like it, but I understand where that feeling comes from.
Paul Booth (Booth is an associate professor of media and cinema studies at DePaul Univesity. He researches fandom in new media and games. His books include Crossing Fandoms: SuperWhoLock and the Contemporary Fan Audience.):
When one is used to being catered to, and then suddenly other people are being catered to as well, it feels like you’ve lost something, even though you actually haven’t. So privilege absolutely plays into this, both male privilege and white privilege.
