The movies are gentle about the attitudes of mobsters! At least the ones I knew! Quite apparently, some are more inclined to have racist attitudes than some, just like any other people (they are people as you and I). It is a thing that has been handed down for generation after generation in my family. Growing up, I remember Grandpapa would turn on the television and yell at the "spooks" and "******s", as he called them (please forgive my language). We were just always taught that they were lower than us in every way, and that is a hard thing to overcome when you were raised in that way.
