Dont waste your time. This is why Communists focus on cancel culture, banning of books, correct political thoughts. You could hire a dump truck, fill it with information, books, writings, links to videos, photographic evidence and artifacts and the cadres will disavow it all.
They dont think, they dont use reason, they only repeat the dogma they are fed by the organs of the party like CNN, MSNBC, NYT etc..
