That never was the case. In RSPW, you had WCW Fans who hated the WWF, WWF Fans who hated WCW, and ECW Fans who hated the other two. There were puro fans who liked garbage, there were ones who liked All Japan, there were those who liked joshi, there were those who liked Juniors. Folks don't want to believe that, but my girlfriend never cared much for All Japan, never really cared for joshi but loved the Juniors in New Japan and MPro. My friend Scott Lacy was more a Juniors and Joshi guy, and not so high on All Japan.
There never was one big group of hippy IWC folks who loved everything and all got along. It was exactly like the real world of fandom: different people liked different things, while some liked a lot of things.
John, I get that it may not be historically accurate. I do think that it works as a useful term to describe some broad trends that a lot of people did have back then. Maybe there's no need for a phrase like that, even if it's not necessarily historically accurate, but I can think of situations where it'd be useful.
The symbol means more than the actual truth in this case?
Could be someone started to use it and then people realized it was a useful and appropriate term?
