The black book of communism inaccurately counts 100 million deaths and is widely cited by every anti communist even though it is blatantly false. Could we make a version that cites 10 times the amount of deaths to use as a reply whenever someone cites it. Preferably without using logic as bad as they use. Just think it would be useful to use in arguments.
Balkan Odyssey made one that is about an hour long.
Hakim made another which is much shorter - around 25 minutes or so.
Those are the only ones I know but both are very good.
