insurrectionist
Definitions
noun
A person who provokes or takes part in an insurrection.
It comes from the Latin insurgo, meaning “to rise up within”: so insurrectionists are, etymologically, the same as “insurgents”, even if that is normally a word for those who do not meekly accept western military rule.
Defining the mostly white crowd that stormed the Capitol on January 6 as “insurrectionists” does more than set a narrative mood, it represents a major narrative shift—expanding the traditional role of the insurrectionist beyond the Black actor to the white one.
adj
Involved in or characterized by insurrection.
The atmosphere was undeniably insurrectionist in nature, yet the police response was languid to the extent that one woman asked an officer when they would be leaving because "they have to fix up."
The insurrectionist movement is mainstream, not simply confined to the political fringe.
