Don't know how either one of these things is correct. And they are two different claims.
Should we pretend that Native Americans don't exist? They are "un-seen"? Is that better? Or should we remove all women from all advertising? Because we don't want to be sexist?
Is there any logic to anything in the world any more?
Do these people want to remove all Indians from America’s history? Is this an extension of removing all southern leadership during the civil war from America’s history?
