My dude, that ain’t even remotely why people are out in the streets. You’re sitting on the sidelines confused why everyone is shouting.
I said that we should take actions that have been shown to improve the situation. 8canwait.org goes over many of them, and I'm sure there are lots of other actions we can take as well.
Zero is impossible without a perfect populous. It is the enemy of 8canwait (and I know, it was created by people who think zero is possible).
Someone saying "zero is possible" makes it seem like they don't understand the situation enough to have a real conversation about it.
To answer your question directly, to address systemic racism in America we need to shift the Overton window of discourse. That _requires_ dissemination of values and ideas which many consider radical or unthinkable.
Beyond that, to say someone is dumb and naive because they don't think cops should be allowed to kill people is callous and ignorant when you consider blacks are three times more likely to be killed by police than whites. [https://mappingpoliceviolence.org/]
"Zero is impossible" is implicitly saying, "Cops should be allowed to kill people." Easy to say when it's not your community in the crosshairs.
