Well, that's your interpretation. Mine is that protected classes exist to make sure their rights are not eroded so that they can be afforded equal protection under the law.

Let me give you an example: In a country with 99% black people and 1% white people employers have a habit of selecting people 'just like themselves' which has resulted in the 1% being vastly over represented in the ranks of the un-employed. An enlightened segment of the legislative branch of government recognizes the unfairness of this and establishes a protection outlawing discrimination based on skin color and creates a protected class, the 'whites'. Of course some blacks will argue that this is in contradiction of everybody being equal before the law, however those people fail to appreciate that this is not an advantage being bestowed upon the whites, merely a lack of dis-advantage resulting in everybody now being equal before the law.

Feel free to replace black and white with whatever groups you care about.
