Let's be frank. What happened to the Native Americans sucked. The federal gov't treatment generally was abysmal and duplicitous.
Let's also remember that they also fought, enslaved and slaughtered each other. That's pretty much the way the world was back then, Whites were just better at it and more technologically advanced.
Many tribes allied with Whites because they feared the Iroquois or the Creek or the Navajo and were tired of being raided, murdered and enslaved.
Pretty much every, state, nation and people have been. Am I to stand around and feel aggrieved because I haven't gotten an apology from the Queen for the invasions of Ireland and Scotland?
Yo! 'Lizbeth! Where my reparations?
“Somebody apologizing for me, without my say so, to someone I never wronged, for something I didn’t do.”
I mostly agree with the the rest of your argument, but you elected the President, Congress and Senate. With ‘you’ I mean Americans, and the elected officials can do a lot of things in our behalf from starting wars to enslaving our kids to the Chinese via debt. An apology for past wrongdoings is a sign of maturity.
