That's fair. It's the bogus nature of the claim, and Sen. Warren's minuscule amount of Native American ancestry, that the nickname mocks. But Donald Trump, whose (very) offensive weaponry tends more to the bludgeon than the rapier, prefers "Pocahontas," an actual, out-and-out racial slur.
The reference sort of misses the point that Warren's claim to be a Native American is bogus. But the biggest problem is that it's racist. Can you imagine calling an African-American politician "Uncle Remus," or a Hispanic senator "Speedy Gonzales?" Using racial and ethnic stereotypes for political opponents is beyond crude and boorish. But of course, President Crotch Grabber is himself beyond crude and boorish. It would be the understatement of the century to say that Donald Trump is absolutely insensitive when it comes to anyone other than Donald Trump. His psychological immaturity is so obvious that only someone completely in denial could doubt it for a moment. It is to the eternal and indelible disgrace of not only of the Republican party in general but of its individual members that they themselves are so dishonest of so lacking in perceptiveness and sensitivity that can continue to believe that the buffoon to whom they give their allegiance is a decent human being, much less a psychologically mature and healthy one.
Well, President Trump did it again tonight, mocking Warren as "Pocahontas" in his speech to the National Rifle Association. I don't doubt that they ate it up. But decent Americans by now can't help but wax nostalgic for the days when the President of the United States was a psychological grown-up, whether they agreed with him politically or not.
