Eh? There's literally nothing good about this story. But the devil's in the details. For example, if a white kid shows up with Bo Derek braids, according to this, she'll be fine. If a little black girl has short braids that look weird, her mom can't add extensions to "train" her hair. It's not semantics, it's right in the story. I hope you don't think I'm making light of it or defending it.
I think it's just a lack of common sense on the part of the school like you say.
But I couldn't help myself...
I'm a prick
