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.
I think you will find as I stated previously, everyone has BS shoved down their throats every single day. Whether it's FOX news, CNN, choose any politician you like, sports commentators, forums, social media, we are totally surrounded by BS being shoved down our throats. What determines how we perceive the BS actually all depends on your interpretation. People asking for equality and not to be killed by the very people who are supposed to be protecting them I personally don't call BS.
Also, when 3 serving on duty police officers openly have a conversation regarding, "Can't wait for a race war!" and "wiping black people off the map" and "I'm going to buy myself a new assault rifle and go out and start slaughtering them F-ing blacks, I can't wait, god I can't wait" Then YES!! I will refer to them as you said "Execution squads" and these are just some that so happened to have been caught on a recording. So when you have the police with this kind of mentality, also prosecutors, judges, prison wardens, I'm not surprised the figures you present are what they are.
And if you can see past this, and all you see are black people bringing this upon themselves I would say that attitude is more of the problem than the solution.
The thing with George Floyd as with Breonna Taylor which apart from the inhumane killings, was the immediate falsifying of the initial police reports which inflamed the already brewing anger. Floyd was passed of as an unfortunate accident, no mention of a knee on his neck for over 8 minutes, no mention of the 8 bullets that entered Taylor's body, YES!! on the OFFICIAL police reports, a blatant systematic cover up which I would imagine has happened so often it's just the norm, hence why it happened without even a thought of the consequences.
And to say you're not really onboard with stopping police brutality until they stop killing themselves is a very weak argument to hide the very thing these protests are about.
And defunding the police doesn't mean disbanding, get it correct. What it means is rather than spending all this money on riot gear, etc, (I still don't understand how the medical services were in such short supply of life saving equipment, but the police look like futuristic, state of the art storm troopers) which in all sense and purpose usually aggrivates a situation with the sight of all that military hardware, spend some money on specially trained mental health experts for instance. So instead of calling on impatient, inexperienced, heavy handed cop to deal with a person who is in a bad place in life mentally, call someone who will have the time and experience, WITH the personal security to keep themselves, the person and the public safe as an example.
