I don't think people object to equal rights or abolishing racism, people object to having a load of BS shoved down their throats. Supposedly in the US (if you believe the media and BLM) police execution squads are going round killing people as a general trend. Take your paragraph above about black on black crime. Now google "Expanded homicide data table 6 2018" The first result will take you to the genuine FBI homicide statistics by ethnicity which shows you amongst other things that...
3315 white people were murdered, 514 perpetrators were Black/African American
2925 Black/African American people were murdered, 234 perpetrators were white.
Keep in mind that the black population as you stated is at least 4x smaller than the white population, yet the guilty party in interracial murders is Black/African American more than twice as often.
So who is more responsible for not valuing the lives of others?
Do the same with the 2017 statistics.
The numbers are..
3567 white people were murdered, 576 perpetrators of Black/African American backgrounds.
2970 black people murdered, 264 white perpetrators.
Again, more than 2x the number of interracial murders committed.
Whilst BLM were out lionising George Floyd, a convicted criminal, calling for the police to be defunded, David Dorn was killed - a REAL black hero, and nobody knows his name. In Chicago, whilst police were busy with the protests, the city had its deadliest day ever, with 18 murders of innocent black victims within 24 hours. That's what the American inner cities will look like with less police. If BLM focussed on this, the real issue, instead of ignoring it and blaming whites or the system, then more people would take it seriously and be onboard with it. Black lives matter of course, but that should start in black communities.
