as I pointed out to someone who shall not be named (wsnbn) via PM, I used seditious in a broad figurative sense of 'given to causing tumult'; to wit:
1. Of a person or body of persons: Given to or guilty of sedition; in early use, ‘factious with tumult, turbulent’ (Johnson); now chiefly, engaged in promoting disaffection or inciting to revolt against constituted authority.
1596 Nashe Saffron Walden, Thirdly, he is verie seditious and mutinous in conversation, picking quarrells with everie man that will not magnifie and applaud him.

I stand by this after much soul-searching.
