Chaim, my guess is that specific bias per se by Youtube need not have been the direct culprit. Of course Youtube, as a relativistic, secular corporation, is going to have a natural bias against us, but I am gonna assume that sheer weight of numbers is what provoked this banning.
I would assume that there are several thousand Muslims and anti-Semites on Youtube for every one of us. Thus, Youtube support morons probably just got inundated with these complaints and caved in.
