I'm seeing a lot of echoes of the GamerGate phenomenon happening right now, so it is important to revisit this a little, quickly.

Thread:

GamerGate was a misogynist movement to harass women online who were in the gaming industry or interested in games. They organized on message boards in places like Reddit and 4chan and picked targets together.

GamerGate didn't appear out of thin air. GamerGate was a representation of white male entitlement that has existed in our culture forever. In particular, the mantra "ethics in games journalism" made no sense and they targeted people who noted how games have bad representation.

There, already, were weird online groups for angry men:

Incels: Involuntary celebates, guys who believe (stupidly) that they're incapable for having sex with women because women only like "alpha" guys (Chads).

PUAs: Pick-Up Artists, guys who use abusive tactics to wear down women to trick them into sexual relationships. They typically are only interested in women in terms of "conquest" and dehumanize women constantly in their forums.
