Anarchism began to bear fruit with the Makhnovischina in Ukraine, and in Spain in the '30s. Sadly, on both occasions, betrayals by so-called Marxists lead to the defeat of the anarchists, and, ultimately to the imposition of brutally repressive regimes.
Can you point me in the direction of Marxism's marvelous victories from the last 100 years?
An ever-fluctuating sliver of territory in wartime Ukraine doesn't really constitute bearing fruit. How long was anarchism's time in the Spanish sun?
