Republicans, at least Republican party leadership, tends to respond to Black Lives Matter style controversies like this:
"Look, let's be reasonable here. We'll grant that Black Lives Matter has legitimate concerns, but you have to grant that cops aren't always bad."
On the surface, it sounds reasonable. If we were dealing with reasonable people, it may actually be reasonable.
In reality, here's how it cashes out:
"Okay. Your demands are crazy. But if you admit an obvious truth, we'll submit to some of your demands. Now isn't that fair?"
Of course, they scream up a storm about this - and then accept it, grudgingly, knowing that they're making progress.
Imagine if the statement was more like this:
"Look, let's be reasonable here. We'll grant that Black Lives Matter has legitimate concerns. But so does Trump and BLM's critics."
Well, that would be interesting. But the GOP establishment has absolutely no interest in taking that position, because then they'll have to actually criticize BLM - which would immediately pit them against corporations and groups they're eager to curry favor with in general.
It's not 'fair' to roll over, or concede without argument. It's cowardice. It's also the habit of the modern GOP.
