> party that openly threaten violence and celebrates it and openly talks about abusing power if they win (as if that would be cool thing)
I read this entire sentence and still wasn't sure which side you were referring to because this applies equally to "the left" in my experience.
"Unquestioning fervor" is not there yet.
They are scary, because their appeal and promis is "I am gon na be tough and violent and anything else is weakness".
