Connections are pretty easy to see. Yet you laugh it off. Nice.
Kant:
Wikipedia
From wikipedia for Frankfurt School:
Post modernism:
Kant's struggle to the end goal which largely goes on outside the individual's direct experience results in equality for all which is in line with the socialists goal of communism.
Postmodernists of the French New Left and the Frankfurt school did not identify with the old-guard Marxist ways and they revamped their action on the campuses toward a similar struggle replacing the old class warfare with cultural warfare.
Kant also heavily wrote on the idea of duty to the other. Taken logically with the dialectical struggle it fits well with both Marxism and the New Left and the concerted efforts of the left behind so many of the social justice movements of the current era for their end goal - equality and the destruction of the traditional (patriarchal, white, male, cisgendered, heteronormative dominated) order.
It makes perfect sense that Kant's tomb in Kaliningrad was preserved by the Soviets.
The "Alleszermalmer (AllDestroyer) from Königsberg" would have destroyed also all attempts of materialisms and all CosmoSophies, which put Sein (entity) before BewusstSein (ConSciousness).
