The US obviously isn't perfect. It has a very sordid past. It's just that it's sordid past isn't any worse than others (this is a human problem) and at its best it does stand for something - continual progress.
You are also absolutely incorrect on numbers of Native Americans or blacks killed vs the Nazi actions. The Nazis killed tens of millions systematically, not even counting incidental casualties.
The Native Americans were not systematically wiped out. The vast majority died prior to contact with Europeans due to simple disease. There's really no contesting this, all you can do is contest the numbers. Something like 50+% (conservative numbers) of the NA population pre-contact was killed by disease.
Many Native American tribes experienced great depopulation, averaging 25–50 percent of the tribes members lost to disease. Additionally, smaller tribes neared extinction after facing a severely destructive spread of disease.[2] The significant toll that this took is expounded upon in the article Population history of indigenous peoples of the Americas. A specific example was Cortes' invasion of Mexico. Before his arrival, the Mexican population is estimated to have been around 25 to 30 million. Fifty years later, the Mexican population was reduced to 3 million, mainly by infectious disease. This shows the main effect of the arrival of Europeans in the new world. With no natural immunity against these pathogens, Native Americans died in huge numbers. The eminent Yale historian David Brion Davis describes this as "the greatest genocide in the history of man. Yet it's increasingly clear that most of the carnage had nothing to do with European barbarism. The worst of the suffering was caused not by swords or guns but by germs."[9] By 1700, less than five thousand Native Americans remained in the southeastern coastal region.[4] In Florida alone, there were seven hundred thousand Native Americans in 1520, but by 1700 the number was around 2000.[4]
That of course does not deny the past. The US mistreated natives and exploited them, there is no doubting this.
Donald Trump and Jeff Sessions have literally never publicly made a statement supporting genocide. The gap between reactionary politics and genocide is vast. Has Trump at age 70 ever even killed a man? Where does this idea that he's going to become genocidal comes from? How can you equate his actions (no deaths) to something which killed tens of millions?
