Like they literally just described an extremely well known pastime that hundreds of thousands of Americans take part in every year— except it’s evil propaganda because the Chinese are doing it. Arlington National Cemetery is where our president goes every Memorial Day to wax poetic about how every American soldier ever died for perfectly just and heroic reasons. Civil War re-enactments are huge deals in the south especially. All across New England there are whole historic towns full of museums to remind us how the founding of our country was the greatest thing ever done. There are gold rush towns in California that celebrate the great westward expansion with little to no mention of the native tribes that were massacred in the process.

If you don’t think the American government has a vested interest in demonizing China, you need to pay more attention to what exactly they’re saying.

Ok yeah that's fun and all but last time I checked Americas didn't willingly purge millions of its own citizens in cultural revolutions

Nah Americans willingly purge millions of its own citizens in race wars, class wars, and Capitalism. Much more subtle. Much more civilized.
