Checking out the fascist or pseudo-fascist regimes, I don't think they venerated the collective, unless by the collective you mean the idea of the nation or the fascist movement itself.
I think most people have a pretty good idea of what fascism means, although I admit that a lot of people on the left immediately label someone a fascist (or something as fascism) when they show any hint of ... any of the points indicated by Kritias. I suppose you can say that we are quite susceptible to anything that might sound like fascism.
