It was called a "vomit-in." It should have been called a puke and rally. Either way, in 2003 a group of purging protesters held perhaps the vilest antiwar demonstration of all time. On the day the Iraq war began in March, an estimated 300 demonstrators who were literally sick of war decided to prove it by ingesting massive amounts of milk tinted with red dye, causing them to hurl all over a San Francisco federal building in unison a dissenting action against the U.S. invasion. We get it, O.K. War makes you puke. You know what makes us puke? Public pukers.
