Here is the thing about the Shiloh affair: it is not that it is a racism episode, but it is an episode where antissociality won for all the involved parts. Look at it: you have people fighting, earning donations for their shouting match, and completely disregarding the most basic social conventions of their society.
The thing that is really important about this whole matter is not the racial aspect, but the fact that the average person does not feel constrain by social convention, nor they think it is worth upholding them. As a matter of fact, thousands donated money and took a previously naughty and previously unacceptable side in the whole affair (Shiloh's). It is just a telling sign of changing times and a failing society, where its rejection is just not important anymore.
