Politicians are playing the game, they would never stand for anything meaningful. It's all profit analysis for them.
I think this whole BLM thing has been engineered. It's not a spontaneous protest on black inequality or police brutality, it goes much further. Democratic party involvement with probably many others, are financing this. Makes sense here since it's an election year. If things get completely out of control, they figure republicans will lose. This is why there is such apathy from cities where violent riots take place. I think they perhaps miscalculated how bad things get and how the public opinion might actually turn against the protesters, as it seems to have.
dig deep and ask yourself....why would a PhD from a University contact some low tiered right wing blog no one's gonna read to make a point when there's plenty right wing media w/far more audience & far more credibility (as if such thing exists in right wing media)? You don't think Fox, Breitbart, OANN (lol), Drudge, or hell, even the Wall Street Journal (i don't lump them in the same category as the former) would pick this up if it'd advance the rigthies' narrative? you're falling for some weak as fuck clickbait from a no-name right wing blog. Millions have since before 2016. It doesn't take much to pen a letter. Remember this beauty?: https://www.snopes.com/fact-check/maga-students-video/
Remember when some anonymous person who claimed to be in the Trump administration wrote a piece trashing Trump. Yeap, you sucked up every last word of it.
