A few weeks ago, perhaps as much as 100,000 people marched in Washington to protest the war in Iraq, the existence of the state of Israel, global warming, etc. I noted then that it was statistically insignificant, since the marchers represented at best 3.3% of the population - a fringe movement by any definition. Today, about 9,000 students cut classes nationwide to protest the war in Iraq.
That's .003 percent - 1 in 33,333. If the population were the bloodstream, and the protestors were alcohol, the nation would not only be legal to drive, a blood test wouldn't even pick it up.
