It was whatever you wanted it to be. I had one friend who bought the line that it was about "ethics in journalism" (imagine me doing a concussive eye roll here). He was on the redpill path at the time (luckily pulled back from the edge since). Anyway, I think the melange of ideologies to sample from gamer gate were appealing to people who felt victimised by society, but didn't want to acknowledge their role in their victimisation, let alone how capitalism/fascism/patriarchy actively hurt them and retarded their aims (aimless though these types tend to be).
