Racism wouldn't exist if some wealthy people, along with government, hadn't thought up the term, and then agitated people to fight each other.
I agree that much of the tension in modern society is due to governments and other powerful interests fostering division as a tactic of distraction to leave those in charge free to continue their behaviour of exploitation and dominance.
As per the meme (which has various mutations) where a banker, a worker and an immigrant are sitting at a table with 10 cookies. The banker takes 9, and then tells the worker 'watch out, that immigrant is trying to steal your cookie.'
What DOES exist has always existed, wicked people taking advantage of the weak.
Yes. And from the point above, we can agree, surely, that the powerful, the establishment, work hard to exploit everyone else in order to maintain and increase their own wealth and power. They make the 'normal' people fight amongst themselves.
In the case of BLM, it's political, and most of BLM people don't realize it that BLM is paid for by Soros in a political move to take down certain freedoms that people have... just like Biden is such a political move.
This point doesn't fit with the preceding two points. Surely it is more likely that people who are systematically oppressed and demonised might rise up against their oppressors? For example, if the powerful are so brazen, so open in their contempt, that they will happily sit on someone's neck for nine minutes to murder them, believing that the system allows them to perpetrate such acts.
Those in power seek to remain in power, and to consolidate and strengthen their position. Modern western society is set up very nicely for them. The rich don't even pay taxes. Normal people are to a large extent constrained and controlled already, wage slaves with 'freedoms' that are largely illusory. I may prefer Biden to Trump, but I'm well aware it's a 'choice' between Establishment Millionaire A and Establishment Millionaire B (or billionaire). Contemporary politics is largely a quibbling over minor distinctions. There is consensus on almost everything; Democrat representatives and Republican representatives are often not representative of anything other than the political class.
The rich are already in control; they have no incentive to destabilise the status quo by initiating protest movements, by encouraging the thing they fear most... unpredictability.
BLM is not welcomed by those in power. You can see that by the ridiculously excessive evidence that was required to finally obtain a conviction in the George Floyd case. This is just how much it takes to force the establishment to concede even a little ground.
