Why did colbert report say stuff about P.O.W.'s? why ?

if you have seen it and you are or have alredy been in the millitary it is an insolt to the POW's. They think they are just talking about John McCain but no it is realy a low blow in tv im going in the marines and i think its messed up that they brought P.O.W.'s in to it for "the word of the day" thats F**ked up
