ummmm how are you being silenced by having the right to march on less busy downtown streets where there will be less traffic? it seems if you march on michigan ave with alot of traffic, you will be infringing upon people who are there conducting their business and there would be potential for the protest to be bothering and imposing yourselves on top of everyday people who have to work or decide to shop or sight-see there. you still are having your legal right to assemble, free speech, march, and you will still be on the news - but being on the busy streets annoying everyone does not help your cause of trying to reach out to everyday people, it is only gonna piss them off.
i suppose i will get slammed for this view, but then again i am exercising my right to free speech on this website! the movement needs to include more and grow, not annoy and push away.
