I doubt he was anything compared to the instructor of an Indian Studies course I had to take to fill out requirements in college, she was an AmIndian and I would have no trouble believing the "White Privilege" crap started in her classroom. I didn't stick around for the tongue lashings and picked up the credits another day.
If you are willing to research the topic, there were some pretty sh*tty things done. That is in the past, however; that land won't be given back, the lost languages are lost, etc. Even the codecs containing vast medical (herbal) knowledge the Spanish burned are gone, and no amount of demagoguery will bring those back, either.
There were atrocities on both sides.
My wife's people (Chippewa) lost 10 million acres of land to chicanery by the Great White Father and his minions, my people lost 3/4 of the land grant to Yankees and carpetbaggers, and half of what was left afterwards to unscrupulous judges and attorneys.
No amount of lament will right that without wronging people who have come since. Those who perpetrated the wrong, and those it was directly done to are dead. So, unless people think they should be compensated for something that wasn't done to them by people who didn't do it that no amount of money can set right, I can't see fomenting that anger over it.
Instead, let's look at history, warts and all, and learn from it, rather than set up another group to look back and get angry later.
