What really bugged me about that post was that the girls choose to not follow the dress code, and get pissed when they are sent home. No school wants girls to have a shirt halfway over their breasts. It makes the school seem bad.
If you seriously have that much of a need to dress as a slut as to where you complain about it, you are in trouble and need help.
Getting sent home because you were such a dumbass as to not read the rules should not make you mad. In fact, it should make you feel stupid.
The girl who wrote that obviously didn't read rules, and reacted in an unnecessary, cringeworthy way. She was pissed and wrote that to make her seem right in what she did, and it shouldn't get her positive feedback.
