How did they get to the point where everyone who is to the right of GAF a Nazi. I mean, I joked about it before, but they are calling EVERYONE who isn't progressive a nazi or white nationalist.
Lots of factors, but I put most of my blame on the moderation staff.
It's simple carrot and stick psychology.
Some exceptions aside, if you are perceived to fall in line with the group-think of the moderator you are moderated lightly. If your opinions are perceived as representing an out-group, you will be moderated with a very heavy hand.
Continue this for several years, Intensifying this disparity more and more and you get modern GAF IMO.
