Because these guys livestream everything you're going to see a lot more footage like this:

Of the cop handler grinning as Patriot Prayer wanders around accosting randos. The thing is these guys don't just screw with the left but also random civilians around town. They see the people of Portland generally as their enemy, like getting up in random people's faces and screaming "TRUMP. BITCH" and then if you say anything back they smash you. I would liken it almost to loyalists in Northern Ireland who would stage these provocative marches into Catholic areas to stir up unrest while colluding with police forces.
That was way worse of course, but the dynamic is pretty similar with marches into Portland as it's perceived as a progressive town. You just have to look at how these guys talk about Portland, and most don't actually live there but on the outskirts and across the river in Vancouver, WA.
