Current destabilization of society in the USA.

[Pio1980]

"Antifa" (antifascists) is a relatively loose term for associated like minded collection of individuals opposed to right/far right interests, usually authoritarians tied to moneyed interests. Oriented more to social causes and reform than business and profits as the first priority. Some extremist agitators in the movement may be interested in fomenting an open rebellion, but that isn't the goal of the vast majority, social reform benefiting most "ordinary" folk is.
Likewise, there are folks and groups on the opposite pole advocating authoritarianism under their principles under political, economic, and/or religious priorities of racism and/or Christian dominionism. Advocates of inciting revolt include so-called "boogaloo boys".
It can be assumed that extremists from any movement may pose as their polar opposite to discredit their image/cause and foment retaliation. Any variation of that strategy is possible and likely to be expected.
