troubler

This term carries a strong negative connotation, often implying a persistent or habitual nature of disruption. While it can describe someone who is merely annoying in a domestic or social setting, it frequently appears in formal, legal, or historical contexts to describe individuals who challenge the status quo or incite civil unrest.

In political contexts, the word is often used by those in power to delegitimize activists or dissidents, framing their pursuit of change as mere "trouble-making" rather than legitimate protest. It differs from "agitator" in that "troubler" emphasizes the resulting distress or annoyance caused to others, whereas "agitator" focuses more on the act of stirring up a crowd.
