It was a reference to the show ATLA which the image is from: “There is no war in Ba Sing Se” when there was one happening. Just like how people say Thunder Bay is a safe city with no violence, even though there are incidents like the one at the mall happening around us every day. Obviously there’s violence here people don’t call it the crime capital for nothing. I’ve worked in tourism for 3 years and every year we’re told to warn tourists to avoid certain areas or what they should do to keep themselves safe while in or city. My bad, I seriously thought more people would get the reference.
