We did exactly that one day when the National Socialist Workers showed up in Columbus, Ohio. It was a January 15 (I believe a Martin Luther King, Jr. birthday) and the National Socialist Workers got the permit first.
Absolute stone silence. I'd estimate the crowd outside the fence (yes, free speech inside a security fence; it makes throwing big things nigh-impossible) at over 5,000. And I'd estimate that 3%, tops, were marginally in favor. At that time, as now, short hair, sometimes known as skinhead, was uncommon, and sometimes, but not often, meant a National Socialist Worker or sympathizer.
I, like many others, showed up to see who else would show up. Not much chance for a riot; no easy way to explain why in polite language. If the National Socialist Workers have shown up again, I haven't heard. Refuse to spend a dime on the Columbus Disgrace, or on cable TV - as another poster's tag-line suggest, I do act accordingly.
Defund the left> Burn DVDs - except I won't do even that - it'd put their stuff in my brain.
Watch Babylon 5, season 4, episode 8. Title "The Illusion of Truth". In it, reporter Dan Randall of 36 Hours ... Trust me. Y'all will like it.
Way to go!
