Dude, that's just weak, please keep exposing how you don't have a position. It's without question that those who died on the Trail of Tears were victims of a racist government program, but it would hardly qualify as "genocide". Perhaps you just don't understand what the word means. You certainly haven't read Sherman's letters about his Indian campaigns and strategies. I mentioned the buffalo because Sherman BRAGGED that by exterminating the buffalo they could exterminate the Plains Indians who relied on them as a food source. It was easier for your post-war union heroes to shoot buffalo than Native American warriors (who could shoot back). Although it didn't stop them from staging raid after raid upon villages of women and children, whom they would often mutilate and then parade with the body parts of their "foes". How brave they were!
By today's moral standards, of course, none of these actions would be acceptable. But neither do they correspond to the millions and tens of millions who died under Nazi and Communist tyrannies.
There weren't that many Native Americans for them to eliminate, otherwise it would. Racial extermination is racial extermination, deal with it.
Nonsense. A complete history of the Plains Indians would show that many tribes moved onto reservations (indeed the "reservation" was already their home) and did not suffer large population declines.
Other tribes suffered as much, or more, from white-men's diseases as they did from "massacres" or starvation.
Speaking of massacres, I'd challenge you to demonstrate how more Indian women and children died from Sherman's massacres than white women and children died from Indian massacres.
