That is pretty shitty.
If Detroit is a blight on America, it is that way because America made it that way. That much I can say. The city needs help, a lot of it. If ever there were an example of the American way of doing things; Detroit is it.
Be aware though ; not everyone you think is shitting on your city is actually shitting on it, many are simply trying to raise awareness of what is going on and find ways to help.
