I mean, ill always say that China is worse than the US. But you can find plenty of examples of the US doing awful things to its people too.

Like the MOVE bombing https://en.wikipedia.org/wiki/1985_MOVE_bombing

or The Tusla Massacre that involved law enforcement bombing black neighbourhoods https://en.wikipedia.org/wiki/Tulsa_race_massacre

Or any of the countless of times cops perpetrated mass violence against black people during the civil war era and cracked down harshly on protests.

Or when the did the same to anti-war protestors during the vietnam war.

Or the numerous times they experimented on their own citezens such as MK ultra, The Tuskegee Syphilis Experiment, or any of the dozens upon dozens of radiation experimentation, like when almost 1000 pregnant mothers were injected with radioactive iron, causing many miscarriages and cancers(and thats not the only time they injected pregnant mothers with radioctive material to see if it fucked up the baby), or when inserting radium rods up the nostrils of school children and then observing how their health declined, or when they dosed hundreds of inuit with radioactive iodine to see its affects on the thyroid.

Like I dont think this makes China's atrocities any more excusable, but the reverse is true to. The US really isnt much better than China.
