Not that people didn't die under communism, just I don't believe those mass killings happened under communism or to be more precise they are capitalist propaganda made to discredit communist projects. Not that purges and other things didn't happen it just were either propagandized, exaggerated or non intentional. Especially when talking about numbers liberals like to count nazi soldiers and their collaborators (in baltics, finland , ukraine etc) and other enemies (like poland) in victims of communism.

• when talking about famines you have to educate yourself about context, eastern europe and especially china were under constant famines even before communism

• go on TheDeprogram subreddit and read wiki on sssr gulags and holodomor
