Gamer's traditionally have less political sophistication than a dead dog. Recent highly visible gamer moves have included review bombing Helldivers, screaming about not being able to see both labia t the same time in Stellar Blade, and whatever that Sweet Baby/DEI thing I haven't bothered to look at is. Idk what the scale of this roblox bs is, but i am interested in the phenomena of game rage campaigns where they get extremely self righteously mad over strange, often trivial shit and make it their entire life for a few days. Wtf is happening? Is this echoes of gamegate a decade later?
I think Gamergate and the Alt-Right could be analyzed as the right figuring out how to mobilize masses of people using new communications technologies. Back in the day I was playing a large scale MMO where one of the factions was almost entirely guys who, in retrospect, were very obviously the petri dishes from which the Alt-Right spawned. In that sense your "stain" theory checks out - After that the new awareness that online gate campaigns could cause significant disruption and gain a lot of attention spread and we've seen a bunch of smaller campaigns happen.
