Oh I see so shutting down political speech that you disagree with is OK because you've determined they're "racists"...got it. It's ironic you're against grouping people together and making judgements based on anecdotal things yet you can't see the hypocrisy in lumping together and calling all Trump supporters racists? Does that mean that this weirdo stabber respresents all Sanders and Stein supporters? What about the black clad thugs in Antifa? They're Sanders people too...? Of course not. The Portland Mayor is using this event as a pretext to shut down speech he disagrees with just like all you little flaggers who know when you've lost.
