"pragmatic anarchism" has been a crypto-liberal bs since way way way back.
Remember that Chomsky was against the USSR when it mattered. If he's been consistent about something it has been about being an anti-leftist.
Remember that Chomsky was "anti-stalinist" when the "scary stalinists" with their "hierarchies" were actually fighting for shit with guns in the US, Cuba, Mexico, Colombia, etc etc.
While Chomsky was "saying mean things about the USSR" the CIA was actively killing MLs who in some cases received aid from the USSR around the world.
Remember that since the dissolution of the USSR world power have taken it to mean free reign to do whatever the fuck they want, which is why unions are non-existent in many places around the world.
All this time, Chomsky has been shilling for "justified hierarchies" in anarco-syndicalist unions who have all cucked out left and right and he continues to shit on actual leftists.
Also he entirely dismisses leftist authors on bogus claims, including Marx, Engels, and Lenin. Plus the entire continental philosophy.
