I don't even know if it counts as "broke away from fascism," since the 4chan of that era really was "progressive liberalism but we get to say slurs." I don't want to defend that position too much, since is and was dog shit, but I don't think it was fascist or proto-fascist or whatever. There was a concerted effort by fascists to take over the space, followed shortly by gamergate, before it became what it is now.
