A famine caused because of his agricultural reforms such as telling farmers to plant their seeds twice as close together to double yield. Or how about killing all the sparrows who were thought to be pests but actually ate the insects. Then when all the crops fail to roll in after harvest you send goon squads out to bully and arrest farmers for "hoarding food" when in fact the crops failed partly because he enforced these asinine policies.

Now if they could recognize shits going wrong then that would help but nobody wants to tell Mao he was wrong about some of his "great leap foward" reforms so they just continue to scapegoat and abuse the now starving farmers.

He did a lot of good things but if your fail to look at the bad things honestly then you are just a fanboy propagandist for autocracy.
