Frankly I dont see anything wrong with the way he said itI don't think any of us are changing our minds Joe based on this. It's a gaff, plain and simple. It was a dumb thing to say and it should have been obvious who heard the line when he was (obviously) preparing it. Words and their use are important, but no, this does not show a character flaw. To me, it's entertainment.
If the left were going to be consistent, they would claim that it betrays a deep seated belief that "others" are inherently inferior....but none of us think that's what it means.
