Who gave you the right to pass Judgement?

I know we all Disapprove when it comes to boys "Saggin" their pants. But I found it quit disturbing that the above statement only focused on African American young men. I have seen plenty of different young men of different races "rock" their pants the same way. O.K, just because the word "Saggin" spelled backwards is "Niggas," doesn't mean its right to point out the an African American is the only ones who does it. Calling an African American a "Nigga" isn't right at all. It's a shame that they're categorized as a "Nigga." Even after trying to stop people from calling each other that, this society found a way to anyway. Do we even know where the word "Niggas" Origins from? If I'm not mistaken it had nothing to do with someone "Saggin" their pants.

Wikipedia:
Nigger AKA Nigga :Nigger is a noun in the English Language, most notable for its usage in a pejorative context to refer to black people (generally people of Sub-Saharan African descent), and also as an informal slang term, among other contexts. It is a common ethnic slur. The word originated as a term used in a neutral context to refer to black people, as a variation of the Spanish/Portuguese noun negro, a descendant of the Latin adjective niger, meaning the color "black".

^{Please tell me does this have anything to do with young men "Saggin" their jeans}
