Go look up to see what China did during the great leap forward and cultural revolution. They killed about 30 million of their own people. I would like you to post a source proving that the United States murdered 30 million of its own people within the past 150 years, as well as persecuting tens of millions of people and sending millions of children from cities to be reeducated with forced labor on camps after being separated from their parents. Hundreds of thousands of intellectuals were murdered for being… Intellectuals.
The only thing that comes close was slavery and the Japanese internment during world War II. However, slavery was abolished over 150 years ago, and during the Japanese internment families were generally kept together and they were not forcibly reeducated.
