Checked out the image of the hamburger in question. As an artist/art
teacher, I am not too sure this image deserves the press it has been
recieving. I took nothing of 9-11 away from the image. Subway has been
railing against traditional fast food for years, but I am unsure that this
image depicts said meaty-goodness as terrorist. I think people are
over-reacting a bit. It is almost as if people are imagining that the
marketing folks for Subway sat down and hatched a plot just to offend
Americans. I think the image is silly, at best. I think the image says
“beware of the burger! It can do harm to you. Eat healthy.” Or it could
mean, “American’s are scum and they deserved 9-11.”
