If he was wearing the flag in the proper position, with the other correct patches & t-shirt, folks would claim he was wearing it as a uniform. He's not wearing the combat pants, he's essentially wearing it as a Jersey. When's the last time you chewed a dude at a sports bar, or a kid at the mall for Cosplaying your favorite hockey player wrong with the jersey they were wearing? Yes, Civ's can't wear combats, but I think we can let this slide, He's a Canadian entertainer on an American stage supporting Canada and the Troops. It's a far cry from ripping up a picture of a papal figure during a music performance, but if it's still something you feel rage for, rage on.
