Yeah I agree, but my reply was running too long. But that's the thing, for us liberal capitalism is "normality", so it skews our view. We see communist history and can easily point to obvious direct causes as "death by communism" even if they contradict communist dogma (eg, Stalin ordering the Holodomor), fair enough, and also see indirect deaths or those caused unwillingly ("famine caused by shitty policies") and group them as "death by communism" which, again, fair enough.

But when we turn inwards? Obvious and direct causes we count as "death by capitalism" but even those we explain away or justify somehow ("the people this US-sponsored Junta killed were not death by free trade, it was a fascist dictatorship!") and indirect/unwilling deaths? Those we don't even quantify (people dead by work hazard? People dead by de-regulation? Famine caused by companies growing higher-profit-per-unit luxury foodstuff since poor starving masses don't pay as much? Deaths by lack of access to healthcare in privatized systems?), we just assume them as "well that's just people dying like normal in society, not something endemic to capitalism").

Which is the exact same mental exercise as some commie justifying Stalin or Mao or whatever as "well that was not real communism, don't blame those deaths on the ideology" which misses the point. We do the exact same but from across the street. Start piling up shit on the capitalist side with as wide a net as we throw on communism (the slave trade, for example: Legally endorsed private ownership over people as commodities in order to reduce production costs, do we add that one up?) and neither side looks particularly better.

One last detail though: It's true capitalism won the Cold War and communist countries barely exist (mostly in name only) nowadays, but don't forget during the 20th Century it was actually a fuckload of people living under that system. Between the Soviets and China alone, I wouldn't be surprised to learn it was the majority of the world living under communism for a couple generations. Just saying it because we also tend to dismiss it as "that weird system some weird countries had for a while" which makes the horrors and deaths look much more impressive. "The system in this one country killed 50 million people" sounds nuts. "The system that ruled the majority of the world for the better part of a century killed 50 million people" still sounds bad, but not nearly as eye-popping.
