Mr. Coen, I say, with regret, you are *mostly wrong. Racism IS primarily about skin color, at least in America. Also, full disclosure,  I happen to be so-called 'white' although there is some confusion :) on certain ancestors. I have, myself, Yes Indeed! been followed around The Captain Cook Hotel due to the way I 'looked'. I have been denied employment because I was (gasp) White! Oh, horrors! I have been subjected to insane levels of racial epithets at multiple job sites, and it was, indeed, because of my 'color'. The 'persons of color' who took great delight in calling me names made that clear. I shared with my good friend/FAMILY! Jeff, who's as Black as you can get, my experience of being vociferously cussed at and called 'cracker' by a black man. We both had a good laugh over it. I cannot get a subsidized house due to my status as 'white-privileged', whatever that is. I've had to claw my way to my present position.

Sadly, you ARE correct, too often... it's just Tuesday for Warren.
