There are two types of graffiti: actual art, and tags which are akin to the forum signatures of yore. The actual art is often a bit strange but can be beautiful, and is more interesting than a bare concrete wall or train hull. But I agree with you that virtually all tags are ugly. And not only that, tags represent an extreme concept of ego, where you subsume the art, spending your entire canvas on your signature.
