Haven't heard any official headcount, but there are guesses running from 100k up to 2 million people who raised a peaceable stink in DC today. Lots of places are showing a cool time-lapse vid of a crowd of protestors crossing a certain intersection. Gives a little illustration of the kind of turnout there was. I saw the vid first at Goomba's so I'll send you there rather than just embed it.
Anyway, when one is on one of the big conservative sites, there are always trolls who mock and deride. One of the good guys will cite the 2nd Amendment or Jefferson's "blood of patriots and tyrants" quote, and then the trolls are start up with the "Yeah, right, like you're actually going to overthrow the government" stuff. This crowd assembled peacefully, for no real good reason except to take a symbolic stand. Imagine this crowd reassembled - not marching symbolically , but angrily responding to actual tyranny. So, trolls, do you still feel the same way? Do you still think that your beloved Big Government is immune to the actions of dedicated patriots?
If History has even the slightest tinge of Justice, the big players in New Media will be given huge credit when we successfully restore our Constitutional Republic. There are many who deserve to be named. Glenn Beck, Andrew Breitbart, Sarah Palin, Michelle Malkin, Rush Limbaugh and others have exposed corruption and abusive government, and are shining an ever-brighter light on all the general BS in DC while the legacy media laments Jacko and Ted and calls us racists. Textbooks of the future ought rightly mention such as these alongside the pamphleteers of old. The left say it is all about ratings and selling advertising, and that their presentations are over-the-top just to garner attention. I'm not so sure. Go read the quotes from Samuel Adams and Patrick Henry. Do you really think they spoke such words in a dreary monotone, devoid of expression? No, I'd wager that the discussions were quite animated. And I can easily picture the David Frums of the 1700s rolling their eyes and complaining about overheated rhetoric and attention-grubbing, and that we need to just tone it down. Mustn't scare the moderates! No! Turn it up! God bless all the quirky bloggers and booming radio voices and weepy Fox commentators who keep the movement moving!
