There was a message. The message was that some racism is born out of ignorance and can be conquered simply by being face with the truth. This is seen by the fact that Jimmy was a racist all his life but came to find a black person that he related to more than any other white person. However, on the flipside some racism is just hatred plain and simple. This was shown by the fact that in Jimmy's mind it wasn't about the color of the skin but the content of the character only to find out when he revealed his friendship with Ruckus that for most of the people he dealt with it really wasn just about hatred of a certain skin color.
If you pull that out and look at it from a real world standpoint it speaks to racism on both sides. A lot of black people think all white people are racists because they don't particularly like a lot of the things that come out of the Black community. When in fact, a lot of those white people don't have any problem with black people that share the same values as them. On the flipside though, most of those white claim that all "racists" are like that when in reality there are a bunch of racist white people who just hate black people for no good reason other than the fact that they are black.
