I can just about guarantee you don't understand humor - fascists tend to be both too stupid and too caught up in being Schrodinger's asshole (don't get all triggered - I was just joking... Unless you want to exterminate the ___s too) to have much capacity for it - it disrupts the irony too much.

I ask because if I start talking about a far-right nationalist group that pretty well checks off Eco's 14 signs, hates the Jewish elite, "sexual deviants", socialists, racial minorities, and has a bunch of members goose stepping around sig heiling, as their leader goes on massive hateful public tirades at rallies in front of a mob of adoring sycophants, people might get the wrong idea.
