This will be my last comment. The fact that the land was stolen from those who were there before you doesn’t mean that you’re disqualified to live there. But you must treat fairly the people who the land was stolen from. That means treat American Indians fairly as all other ethnicities, no better and no worse than any other group.
While I differ with President Trump to a great extent on the immigration topic such as separate families-I think the argument ‘nobody is illegal on stolen land’ is a poor argument because we should still have immigration laws.
The land on which the Sioux lived on was stolen from other Indian tribes, but usually don’t hear that Sioux or other Indian tribes did not have a right to fight for their land just because they stole land from other Indian tribes.

has a right to enforce immigration laws and have borders, though the land was stolen from others as long as they don’t do anything cruel and bad such as separate families or deny care for those here.
If you look @ the Arab-Israeli dispute, Israel was created by stealing land from others who were there before them. But usually don’t hear (except by some) that Jews don’t have a right to live there because it was stolen from others especially the Palestinians. It is important that the Jewish people who live there must treat the people who Israel stole the land from fairly.
Before the Whites stole the territory, Native Americans got their lands by wars, which in some cases, involved killing the neighboring tribes men and kidnapping the women and girls as wives. In these cases, the defeated tribe didn’t get a reservation or even a bad peace treaty. The men are killed, most boys are killed (unless taken as slaves) and the women and girls are kidnapped as wives.
Now yes, the Indian reservations where Whites take the best lands and treaties broken, is arrogant, esp. when 1 wants gold, silver, etc. But here, you are alive and you or descendants have a chance. An American Indian can get married, raise family and they or descendants have a chance to change things for better because you’re alive. Indian reservations was often arrogance, but a case can be made that it’s the lesser of the 2 bads because here you are @least alive and have a chance.
An Indian war, where 1 Indian tribe kills another tribe, takes women and girls as wives, the men being killed unless the boy becomes a slave is worse because here the defeated tribe doesn’t get a treaty & thus as the men killed don’t get to marry and raise a family, you have no chance.Treatment of American Indians was arrogant only that potentially, some American Indian tribes would’ve hypothetically have done the same thing if they had the better weapons and military strategies.
With wars, including stealing land, you must have courage to fight for your greed. Axis dictators charisma indoctrinated millions of German soldiers, Japanese and Italians to fight and die for their leaders. There have been other ideology wars such as Korean War, Vietnam War, etc.
