I've been very angry my entire adult life about the injustices of the US prison and policing system, and would welcome constructive discussions of how to reform them. This is not that. It is a cartoonishly astroturfed Democrat fanfic "grassroots" movement intended to spread rage, fear, and fuel partisan politics at the national level while doing jack shit at the state and local level where the majority of these issues arise.
The topic has become too toxic for any actual discussion of workable policy without social liquidation, so we just get screeching about abolishing the police and fantasizing about the army massacring peaceful-ish protestors instead of undoing the ravages of the war on drugs, reducing prison sentences for non-violent crime, dismantling "zero tolerance" policies, mandatory minimum sentences, three strikes laws, etc, and addressing poverty and community collapse.
I have much political common ground with the protestors regarding police reform and have for decades, but nothing good will come of this. Demanding unworkable feel good measures are a major part of how we got all these awful policies, and there's a good chance we're going to get a mix of tough-on-crime reforms due to the riots that weren't dealt with due to optics and race-baiting bullshit that ignores the root problems of police brutality.
You, and most dems, conflate disagreement on how to fix things, or any opposition whatsoever to the craziest slogans being shrieked, with thinking the status quo is good, because if you talk policy, you lose your wedge issue, and so does the GOP.
