1. The numbers of single, childless, and in many cases white young adults participating in the riots indicates more that just hopelessness. Given a green light to destroy, many will.
2. Which leaders? Many of the thought leaders on the left, cited and lauded by media and political figures, are doing no such pleading. And I'm not sure a single (D) politician has condemned Antifa. How many Republicans have condemned the white supremacists? (All of them, including Trump, who is awful).
3. When you define racism as "far right" it becomes hard to find racist leftists. If you include "the soft bigotry of low expectations," as Sowell describes, the left is overwhelmingly racist. It doesn't help that we are redefining racism to fit a progressive narrative.
Couple all this with the fact that the data completely disproves the narrative of systemic police racism targeting and killing black people, and the whole thing becomes impossible to resolve.
You can not, under any circumstances, have a productive discourse if the facts are treated like lies, or worse, if presenting the facts makes you racist. Unfortunately, the public figures of "your side" are not engaging honestly in the debate, as you are.
