he is right. There are basically no examples where changes were driven by the majority. Obviusly, you need a substantial and dedicated minority. But for examples, bolshevism won because a minority of the oeple of st. petersburg were willing to support Lenin. probably it wasn't eveen close to the 1% o fthe total population. in 1930, when the fascist party was well established as the only political force in Italy, his membership wasn't more than 10 million, on a poulation of 40 millions (obviusly prior to the march on Rome there were evn less fascists). The american revolution was made by a tiny group of people, and the French revolution as well was the result of a fraction of the population of Paris willing to support the revolutionary government. So yeah, in most cases, you just need and organized minority at the center of the events.
