Economic policies and corruption have caused lots of people to die in lots of places.
Spewing hate at other people online will never make the world a better place. There’s more than enough of it already.
Instead of rabidly hating each other if someone doesn’t use the words you like, why not all try to be better and do better.
If it’s never “real” communism because for it to be “real” communism it has to take place in an ideal civilization where all people are pure and good and no person would ever abuse whatever authority or power they have over distribution for their own personal gain… that’s an inherent flaw.
It’s the same inherent flaw that turns capitalism into child grinding factories. You have to take human nature into account. They’re always going to be shitty people, and shitty people tend to like getting themselves into positions of power.
If for an economic ideology to be actually viable All humans must undergo a lobotomy beforehand it’s useless in the real world.
