Not all native nation no, and if their land had not been stolen, They could still be doing so now. And this does not compare to the genocide they suffered. They were all present on the land and fought among themselves with arrows. Invaders came with guns and rifles. How they lived before has nothing to do with the genocide they suffered at the hands of invaders. Where not the Europeans at constant war between themselves too?
If you cannot see the difference between internal and invasion, Your moral compass is broken. Try thinking.
