I think the bullshit in Portland is finally a bridge too far for many people who've previously expressed support for the 'protests'. Even the mayor is trying to sound tough after the rioters attempted to burn down a police station with staff hunkered inside. It's hard to get a pulse on the reality of things in the USA when all the media, both traditional and online, is nothing but hardcore propaganda and manufactured narratives. You can't even trust online comments for the most part because everything is so heavily censored to slant the discourse a particular way.
I'm not in America so I'm probably a bit out of touch, but I see this election turning into a repeat of 2016 insofar that the polls are dead wrong about Biden having any sort of meaningful lead. These riots are a gift to Trump. But as entertaining as they are to watch, it saddens me that the USA is having to deal with this as I don't believe for a second that any of it's organic. Many of the hardcore rioters are going to be surprised when they're slapped with criminal charges in a month or two. The amount of video taken at these riots make it a real challenge to get away with spur of the moment felonies while surrounded by 100's of people.
