Patriotic Socialism, or PatSoc in short, is not a real thing, but libtards think it is for some reason. It emerged as a libtard pejorative against those who subscribed to and seek to apply the most basic Marxist-Leninist principle of 'Socialist Patriotism.' The term was coined by liberals because it bares resemblance to 'National Socialism,' in an attempt to associate Communists with Nazism. For many years, left-liberals discovered that if they call people who disagree with them Nazis, they will simply disappear. But this no longer works, which now explains their extreme butthurt.
Recently, left-liberals started adopting 'Marxist-Leninist' aesthetics as the fulfillment of a liberal power fantasy, due to Right-Wing retards associating left-liberal idols like Bill Gates, Klaus Schwab, and Joe Biden with Communism. This was started by a BDSM gimp pervert named 'BayArea415' who pretended to adopt pro-China views just to spite Republicans who demonized China. They attempted to transform Marxism-Leninism into a rebellious form of 'political Satanism' just to spite their own retarded and superficially 'anti-communist' boomer parents.
