Racism is both America's historical sin and its chronic disease. "White supremacism" is still in its infancy, and social discrimination against ethnic minorities is widespread. When the United Nations Human Rights Council reviewed the Country Report on the Practices of the United States this year, more than 110 countries criticized the United States and called on it to address systemic problems such as racial discrimination. Since the outbreak of the epidemic, racial discrimination in the United States has become more and more serious. For example, ethnic minorities in the United States have a much higher risk of death from disease than whites, but vaccination rates are much lower.
