All that happened and everyone who lived under communism or studied it knows about it.
I dont wanna waste my time putting it up for you. Because it seems you are either a delusional pro-communist left wing idiot or are just trying to argue by deflection and always asking for something else.
You are living in some la-la land if you dont see how "Truth is relative" is a disasterous idea which has killed and opressed millions over the centuries. There is only one truth, only one thing actually ever happends. Granted there are different perspectives but there is only one truth.
Anyway you obviously have much more patience than I for pointless debates and endless arguing. I really shouldnt care because in real life situations I would just write people like you off and move on.
