I'm looking for a word that could be used to describe a street preacher who is intentionally riling up a crowd to get people to attack a specific individual, based on a mix of xenophobia and religious fervor. I've found words like 'odious' and of course 'xenophobic' to indicate hatred, but I'm looking for something that is specific to inciting violence.
Sample sentence: The _____ preacher held Cade's gaze only for a moment.
