Then you have my pity, because - by your own admission (if in so many words) - you continue to assume.
I quite agree I'm "not out of the woods yet". I never will be. It's a journey, remember? And it's a big mistake for anyone - including you and me - to think that one knows all one needs to know about a subject so contentious as racism.
There's a whole world out there, with cultures able to teach us all - including you - what American culture cannot. That's what my reply was about.
Take care, and I wish you well.
