We’ve actually had a fair bit of popular culture about Soviet atrocities, thanks to the Cold War and Solzhenitsyn. A lot less on China, unless you follow travel bloggers or go to a lot of international film festivals. More US people probably get frenzied over the annual dog meat/ cat meat festival in China than over the fact that 45 million people were killed there.Compare all the movies about the Holocaust to the amount of movies about Soviet and Chinese atrocities.
