Utterly disgusting!

When I was on my way to work this morning, I came across this utterly disgusting scribbling made by someone unknown;
I dont know if its allowed to upload a pic like this one, but I felt I had to just because everytime I come across things like that it nearly makes me vomit.
Yesterday I was watching "The third wave", some of you might know that experiment and film and once again I realized how fragile peace, humanity and justice can be and in what an ignorant and offensive way mankind is able to act.
