I feel like both of these perspectives aren't entirely mutually exclusive, though I'm not exactly an expert on the matter. Left wing unrest is organised and focused, which is why it isn't as destructive as it could be, since there's a lot of emphasis on maintaining optics for the media to glorify. I don't exactly agree that it isn't coordinated, though I think what triggers them is spontaneous before it's quickly subverted and capitalised on, see any race riot.
Whereas right wing unrest can't be organised due to the government's laser focus on preventing any major right wing groups from forming in the first place, hence most of what you see are lone wolves and mass shootings. But I do also think that if there's a trigger for right wing unrest like there are triggers for left wing unrest, though a lot more rare since it takes a lot to rouse the right from their usual complacency, you see the type of destruction
@Gehenna mentions- an actual revolution unlike what the left claims their riots to be.
All that said, I really don't know what it would take for that to happen on a massive scale to the point it transitions from lone wolves to mobs, feels about as likely as finding a unicorn, but 2020 has been a steady source of stress that's been building up for the right in particular, so I won't act like it can't happen if Biden ends up winning, though I'm still skeptical on the likelihood.
