Sometimes you do have to fight for what you believe in, but there's an important time and place deal and most of the time violence should only be a last resort. Rioting among thousands of peaceful protesters who are delivering a message in literally one of the most progressive cities in the nation that are far left and anti-Trump and were allowing the protest to happen until the violent outburst by a fews elect anarchist and causing destruction to the city in question is neither the time nor place. It is obviously just shit stirrers at that point.
But the pacific northwest has had to deal with these extremist for a while. While the Pacific Northwest is very heavy left overall, there's a lot of buck nowhere nature around here, a strength and weakness in this case as Oregon and Washington as they continue to fight hard to preserve nature around here, but with all that empty and scattered land it does let some extremist groups foster mostly undisturbed. Famously there are some neo-nazi and KKK groups the outskirt around Portland. Most of the population of Oregon is very centered on three cities, Portland most of all, and the rest of it is mostly nature and small towns. The populated areas are far-left, and they make up about 80% of Oregon's population, but the rest is fairly right but scattered and the population of all of them together is only a small fraction of the big cities in Oregon. But due maybe in part of this, when there's peaceful protests in these areas, they have famously been soured by the act of a few sudden extremist, unfortunately. It's an actual issue of the area.
