The point is that people who proclaim themselves "antifa", be they in dictatorial power over half of Korea, or merely a band of organized activists, are not automatically due credibility and trust because of some grammatical fixation that magically guarantees alignment. Do you only become skeptical when the message is twisted after winning power?

"Antifa" factions in the Spanish Civil War ultimately did not win and accidentally enable a Spanish DPRK, but they still were perfectly capable of being and doing evil, such as committing mass rape and shooting of nuns.
