Native Americans were not slaves as a group when Europeans arrived, but had been in North America for thousands of years, and that status made them legal owners - based on your logic, Europeans (i.e. white people) own Europe. If any people of colour own their own house in a European country, well, sorry, you gotta give it to me because I'm European and you're not.
I belong to one group, Native Americans, I am 1/8 going back to my great-grandmother. Do I qualify for reparations if that ended up occurring? I don't know but I don't need the money. But, I would like a public apology in writing in the official history of the United States government official statements - hang on a sec, why should the US government apologise to you?
You're 1/8 Native American, so what ... you don't speak an Indian language, you don't live under the culture of your great-grandmother. Your religion is not the same as your great-grandmother's tribe.
I can see that there may be a solid case to be made for an apology by the US gov to full-blooded Indians (especially full-blooded Indians of the past, e.g. your great-grandmother) ... but to you?
