The quote from the news article "wearing her hair in a natural African-American hair style"....... say what? Curly and all puffed out is a natural African-American style? What the hell does that mean? Their hair naturally became like this as a result of their being Americanized? What, is it the water that does this? Where do they find the morons that write this stuff?
Now, to the meat of the story. Whoever made that decision at that school has about the same size brain as the one's that enforce the zero tolerance policies for finger and pop tart guns. If that person were in charge of my kids school they would be out of a job or my kid would be in a new school. End of story.
I think it simply means that she takes no effort to alter what her hair's natural state is. And that natural state is due in large part to her negroid genetics (mods, please don't ban, that's the proper term). The use of African American is simply the PC/layman's way of identifying her genetic race.
