You're letting yourself get pretty twisted up on this topic. That's what happens when you're confused or brainwashed. Or both.
The article you posted was referenced in the one I posted as being inaccurate. How did you miss that? More specifically -- and to put it in kindergarten terms for ya -- there's a difference between something that's rude and truly prejudice. You're unable to see the difference, apparently.
To quote the NY Law Journal ... "there is such a thing as being oversensitive and imagining prejudice when none exists." This is where you live, my friend. I hope you enjoy your life experiences as you look at the world through a tainted lens. And you, or people in general, really shouldn't try to force your narrow, misinformed beliefs on others -- lest you come across as a fascist.
And ... back on topic. If Doyle vs Shemy is somehow comparable, I find fault in both dudes for sure. IMO, Doyle got exactly what he deserved after years of being a dickhead and certainly biased if not racist. And Shemy ... well, how dumb do you have to be ... jesus.
