And as a follow-up, watching the Portland protests yesterday and the coverage via the Oregonian, Willamette Week and Portland Mercury, it seems that the majority of the violence in the Rose City was committed by Antifa and various leftist protest groups who threw bricks and various projectiles and attacked police and Alt-Right guys.
Which is rather at odds with the tone of this article and media coverage. 
Sure, you can disagree politically with this upcoming Westlake rally. And the folks putting it on might be a bunch of low IQ knuckle-draggers with poor impulse control. But I fail to see the need for Antifa and various leftists to engage in violence and property damage because a bunch of Alt Right LARPers like to dress up as Spartan warriors or as an autistic Stick Man and wave Gadsden Flags..
But - as always - this advice will fall on deaf ears.
