We're a dying species on a planet that will heat up until we're all gone, do I really need another horror story ?

You mentioning the chekist is just the old and tired whataboutism where you point out horrors committed by the Soviets to justify your point of view. I could give you horrific stories where people were tortured and/or killed because of corporate greed and/or imperialism. What good will that accomplish?

Will hearing that people were locked inside a sweatshop while it caught on fire change anything about your view of capitalism ?

People falling in poverty because they can't pay medical bills, killing themselves because of their job, getting tortured for information they don't have, seeing their leaders get overthrown and living in a military state because of that.

Are you capable of seeing the horrors wrought by capitalism, not just those in the past but also those we see every day, and answer the question "Would that have happened if the redistribution of resources was fair ?"

If you want a movie recommendation "Sugarland" (2014), it's just a fun movie about sugar, showing how insidious and pervasive capitalists can be, don't worry no torture porn here but you'll still feel like shit at the end.
