Social Fascism was a terminvented by the Comintern in the '30's. It has evolved since then from meaning democracy as an open door to Fascism, through all sorts of Sociological and Political filters to have many meanings. The sense in which I at one point used it was related to social cohesion, small town mentality or group identity.
