Also depending on who you talk to the 2020 riots were protests. Not riots. 

Both sides like to do false flag accusations as well. Which has been proven in a few cases. Like cops or proud boys dressing in all black to look like antifa, getting property damage started and riled up, then saying “look at the rioters” when it would have otherwise been a largely peaceful affair. 

There are also opportunists who you can’t fairly assign to either “side”. They take advantage of the goings ons to smash/grab and do chaos. The right likes to associate these people with the movements they operate around, but it’s disingenuous

The opportunists don’t do anarchy. Anarchy is a range of political theories. It is not a state of chaos, for which the proper term, by the way, is anomie-not anarchy.
