So, basically this boils down to the Left accepting "difference" and making nice with even reactionary fascists in order to expand beyond it's "bubble" & let in even the most retrograde fundamentalists for the greater goal of "class solidarity".
Sorry, but I don't think so.
In fact, doing this at a time when almost every liberal to socdem political tendency is bent on throwing marginalized people under their buses to jump on the fascist bandwagon, is political suicide for the Left.
