“Terrorism” as commonly used (suicide attacks etc) is, in fact, asymmetric warfare. And in emotion it’s an individual going against a mass. It’s the opposite of fascism.
“Terrorism” as Stalin’s repressions, or jailing random people for words, or police not touching violent groups harassing someone, etc - yes, these are normal for fascism.
The links, which you clearly are refusing to read, so I’m not sure why you’re telling me what’s in them, show that asymmetric warfare in the form of terrorism was exactly what brought Mussolini to power.
Again, I know that you will never say you were incorrect (I doubt you ever do), this is for the benefit of others.
