The problem?
Too much peace, comfort, boredom, time, and decades of being an epicenter of far-left progressive ideology. They don't have any real tangible problems so they seek enemies wherever they can find them; even if they need to create them themselves.
For the most part, these aren't the "people of Oregon" but more bored youth who are children of the local liberal elite. How else do you think they could possibly make so much time for these activities? They're comfortable enough financially to be able to afford it -- even as they panhandle for donations. For some, this is their job. This is how they make their money.
They don't have a cause. Their cause is themselves.
