Excellent article.
As in an excellent example of how identity politics is succeeding in drowning us in a toxic pool of mistrustful race-baiting. 
Remember Martin Luther King?
"...not be judged by the color of their skin, but by the content of their character." 
MLK and others pointed us down that road where race wasn't supposed to matter. 
It wasn't perfect but it was clear that white supremacist hate was increasingly falling  behind mainstream society.
The KKK was a tiny clown show.
Groups like BLM have trashed that dream. 
Divisive pigeon-holing by colour, religion, gender or sexual preference. 
And then under the spurious label of "social justice" each group is subjectively ranked according to historical suffering (real or imagined) or guilt for past sins (real or imagined). 
They expect that freedom of speech or legal justice be adjusted for each group in accordance with those rankings. 
They subscribe to the lie of "good racism".
They've allowed Hate to catch up.
Sad.
