Its a moot point, the city of Portland and the people who organize the protest came to terms a few years back, this allowed the police dept to block off streets and pick the route the bikers would take with stipulations on pre-drinking and such and avoid conflict between police and protesters since this agreement from what I understand there have been no issues. I don't even know why were having an argument because the city of Portland clearly accepted the protest lawful or they would not assist with the blockade/motorcade and route.
But ultimately this is why we have to refrain from having these discussions now a days, people can't respect other peoples opinions, there used to be a time when people could disagree and be respectful, maybe because back in the day it was a face to face discussion now people can call you names and belittle you because there is no human interaction or reaction.
