One big problem with Gamergate in terms of understanding it and discussing it is that once the preceding events had turned into Gamergate it was actually about a number of different things. By the time it had become Gamergate it was a full on Internet flamewar between Gamergaters and Social Justice Warriors with each side needing to buy wholesale into the full manifesto of their side.
This means that even now if you try to critically examine either of the sides, unless you're able to completely commit to that side, or to the opposite one, you'll be perceived as some kind of horrible traitor. That said though, the Gamergater side seems to be the one most consumed by hatred and prone to making violent and misogynistic threats.
I went looking again and found this academic article. It's not too bad, although it's long and very light on the details of events:
journals.sagepub.com/doi/10.1177/2056305116672484
(But it does tend to assume that progressive forces are good and reactionary forces are bad.)
It fits into what I wrote earlier. The problem isn't that gamers are bad people, it's that when a strong identity that requires compliance becomes part of being a gamer you might end up with a problem. Gamergate at its heart was an identity war.
