Quite often, the surest sign of a budding fascist movement is its tendency to proclaim others as tyrants, useful idiots, and as a "threat" to traditional values. It's a playbook right out of Mein Kampf, Leninist tactics and yes...Mussolini. Cry wolf about the other faction and resort to tactics that undermine democratic values....like stealing delegates through rule technicalities. Invars tactics are akin to the ways in which Goebels would seek to manipulate Germans into seeing the Nazis as victims of unfair dealings and thuggery. So if any such comparisons are to be made....there you have it.
But that said, any such drawing of parallels is absurd...it's little more than shallow hyperbolism and I engage in it above to make that point. So again, anyone who...in seriousness...draws an analogy between any of our modern nominees and fascism, simply has no understanding of history OR politics.
