I'm extremely uninformed about history. In my experience, how it usually goes with shit like this is that it wasn't nearly as bad as Americans and American media portray it, but a lot of shit sucked massive balls. Many times, actions were "justified" because of various reasons, but put in practice, stuff like ignorance, power struggles, paranoia, and just human ineptitude gave a lot of ground for corruption and terrible shit to go down.
Not surprisingly, little comparison is made to current times third world countries, because people live like shit and communism is unambigously better for the majority of it's civilians. Muh jeans, muh jazz. Doesn't even fucking matter if you have stores that sell jeans if you work 2 jobs, get mugged every other week, and you personally knew people that were murdered on the streets.
Even the third world is absolute shit, it's just not visible.
Reminder that communism has worked pretty fucking well, despite the myriad of problems it had.
