The playbook is the knowing look and the consistently not reaching conclusions, or perhaps not amongst polite company. They're quite free to think differently to me.

If they had said that the protests were fine but next time we expect a shout-out, then the discussion could move on. Much like in this example.

Thank you for this thoughtful and well-reasoned opinion. I would also like to add a global take into the discussion. Who stands to benefit from the American people being both divided among white / black, male / female, old / young, and distrusting of the media? Certainly not anyone in America.

Not OP. When considering this line of thought, I think of meme's in the original sense of the word. So one could take a mildly-conspiratorial take on it and say that the "meme" itself stands to benefit from this sort of division rather than a nefarious agent or group. It's a self-feeding cycle because I would argue that this cause done in a bad/unfair way sows more racial/gender/etc division and as such creates more reason for itself to exist.

> Police brutality is wrong and there is reason to think that it is a worse problem for black people than for white people. At the same time, we recognize the disproportionate extent to which white people suffer from black violence. We may perhaps disagree about the extent to which the discrepancy is due to systematic racism or socioeconomic issues, but we recognize your concerns. We want to reach across the division and work together to fix all these issues

So you want to dilute the protest which is specifically about police violence against black people into something entirely different? You're essentially arguing to destroy the entire protest for something it's not at all about.

Protesting police brutality against black people is protesting police brutality in general.
