You're talking about this oft-shared video, I imagine:

Yea, wow, those protesters really did a number on that guy. Obviously he was just defending his shop from Thugs, right?
Oh wait... no. He was a crazy person running at protesters with a sword:

And look at that, those Thugs, after protecting themselves from him, then took on the role of First Responder, and started treating him:

The second link doesn't seem to have any video. But head-kicking beyond the point of unconsciousness is not how I would defend myself from a crazy person (if that's even a factual take).
The third link is hard to interpret, but until someone analyzes it, I assume that the people assisting the guy are not the same ones that were committing wanton savagery. But bless them, in any case.
I turned to my wife after seeing the first video and remarked, "These guys just gave the fall election to Trump.". If you're old enough to remember Nixon, you'll take the reference.
