That's the point of these marches. To deny access and intimidate people who won't recognize their agenda. If they were interested in other peoples rights they would hold the demonstrations in a public park. Portland has 279 parks, more than most cities of the same size. What happens when people just start driving thru these illegal demonstrations without stopping. More than likely they end up being shot. How's that for being able to use a public street for it's intended purpose? But then, it's Portland. I know people who live there. It isn't Kansas City or even Denver.
