You assert that the groups responsible for the rioting were clearly differentiated from the BLM protests, but I don't see how one can differentiate them without making a no-true-Scotsman argument that the rioting somehow goes against the principles of the movement and they can be distinguished on that basis. At the time, some people were claiming that the rioting was the work of alt-right agents provocateurs, but that doesn't seem to have panned out. (Cf. the assertions that the Capitol rioters were antifa agents provocateurs.)

It's also not a good argument given there were loud voices claiming to speak for BLM that were justifying the rioting and looting. Reparations, smashing the racist capitalist system, etc. Maybe they don't represent the movement as a whole, but if so, the movement had lost its voice to extremists by that point.

An example of this kind of thing, posted by a friend who took part in BLM protests, in response to a status update I made: https://pbs.twimg.com/media/EnCI4_9W4AAAxDf.jpg

Bad actors doing embarrassing or destructive things is a real problem for ad-hoc decentralized movements. And that's why I'm careful to not hold the acts of individuals against a movement unless said acts are the whole point of the movement. But at the same time, "Black Lives Matter riots of 2020" is the most accurate label for the events in question that I can think of.
