Last time, it was the KKK marching on Washington, hoods, crosses, signs and all, scaring all the black and catholic folk to death. It's just amazing how most ideas aren't that original. I dont' think this is a good idea - even with silencers. Articles make me think a lot of the dot-com backlash is simply the kvetching of the perpetually pissed off. If they weren't complaining about Jeff Bezos, they'd be complaining about something else.
Nobody likes people who spend all day everyday, fuming, fussing and fighting.
I think we should all wear white t-shirts and hold up blank signs. Pretty soon members of Congress will try to one-up the prez to see who can stay out there the longest without snapping. My money's on Strom Thurmond, who will most likely not notice the crowd. Soon, members of the media and celebrities will get out there just to see if they can handle the pressure. Bonus points if the crowd can be convinced beforehand to grin maniacally when a Baldwin brother shows up.
