[quote=@mdk]If we're gonna hate people over history, we should start by tracking down everyone who's worn a Che Guevara shirt. Symbols only carry meaning when people attach it. If we could just, you know.... stop attaching the worst possible connotation to every possible symbol we don't like? That might clear a lot of things up.

This.

If we banned every symbol that has ever stood for something wrong, or that someone else disagreed with, we would be banning every symbol that has ever existed or ever will exist.

I'd also like to add that, as an inhabitant of Western Canada, I see the flag in question bizarrely frequently—most often on pick-ups. It doesn't seem to stand for anything here other than, "I'm from a rural area".
