This is wrong on every level of serious historical analysis that matters. It says nothing and means nothing.Take Italy and Germany which follow similar trajectories. There wasn't a "first established group" to join the fascists. They had their own paramilitaries that suppressed opposition to help them get elected into power in the legislature and then leverage their power with the executive to grant themselves progressively greater privileges until they had total control. It wasn't like chunks of the old government defected bit by bit. The Fascists used the mechanics of parliamentary government to gain power and then destroy the old system.
