So there aren't any.
I follow that account and have never seen any instigation of any violence of any kind. More likely, a certain "side of the political spectrum" has decided that redefining language is a good idea, and making anything they disagree with "violence" seems to be a defining characteristic of that group. You added "extreme violence" to double down on it, but faking outrage doesn't help the discussion any.
It isn't true, it's sophistry.
