I do think that one possible outcome of this is that games media will experience a schism along political lines. Games are going through a tumultuous adolescence, and it's now impossible for them to go back to the way things were where everyone pretends games are completely a-political.
However, I do think that the fact that most of the games media was more or less on the side of social justice (which is a good thing, in my opinion!) created a bottled up anger in everyone who didn't feel represented by most of the media outlets. I think this has been building up for some time, and this was the spark that ignited things.
So, going forward, I think we'll see the growth of "Fox News / Rush Limbaugh" game journalists to capture the audience that doesn't feel they're being served by the "MSNBC / Jon Stewart" game journalists.
As a progressive person myself, that will be weird to see, but I think it's inevitable. Best case scenario is that the people who gravitate to one side will not feel so under-represented, and less underground ugliness will happen.
