That is a pretty wild generalisation to make. From me claiming one person that pretended to be a communist wasn’t to somehow me being a… Soviet fanboy or something? Stalin and Mao both committed atrocities, pretending to be something they aren’t. China keeps doing it to this day, as does DPRK. Lenin wasn’t a saint folks over at .ml pretend he was either. People get corrupted by power, it happens depressingly often under any political ideology.
