But but... North and South was an awesome game, taught me so much about the civil war... like you have to march single file over bridges that are half destroyed...

In all seriousness, I agree with /u/NinjaKlaus, if it's in a historical context then it should be fine. But then that also opens up the argument that the shooting is now a historical event and the flag did play a part in it, so technically it would be allowed by that rule. Baaaaaah!

Edit: I'm offended by the icon, please have it removed.
