Growing up in Greenwich Village with a mom who was in High School in the 1960s, you hear a lot of anti-war songs. One Phil Ochs number (covered here by Arlo Guthrie) is called "I Ain't Marchin' Anymore." Here's the gyst:
For I marched to the battles of the German trench
In a war that was bound to end all wars
Oh I must have killed a million men
And now they want me back again
But I ain't marchin' anymore
In today's anti-war movement, though, these words take on a different meaning. The Reason TV video below shows it well, but the conclusion is that since Bush left the White House, those protestors don't feel the need to march against the wars anymore.
