To be very honest, I really don't understand the hubbub. Some teacher requires students to read a rather hazy book (which by the looks of things would leave me stranded on page 1), which is then overruled by the headmaster on grounds that it contains profanity (and not pagan elements, although that is of course another, if unspoken and denied, reason). And students can't be made to read profanity by requirement.
Is that it?
That's quite a double-edged sword, because we are dealing with Art (notice the capital A) here, and then profanity is no longer profanity, although there are boundaries you should not cross. One Dutch artist, living in Kenia, openly talked about screwing his models, all of whom were well below 18 years of age. That that made him a paedophile was something he always denied: it was Art (or, in his case, après-Art). The Keniese police did little (imagine that), but (Dutch) readers of his interviews were not so forgiving. The monster is now safely behind bars.
I remember that while in high school, I had to read a Dutch homo-erotic 'masterpiece', and there is another memory about our teacher reading out a short story about a young guy hiding a dead grasshopper in the Easter lunch, and doing it with a chicken, all in response to his dads religious ways which were written in stone. A few months ago I glanced over an interview with (I think) a Persian writer, who was doing similar things but then from an islamic point of view: the nearly-adult son of a mullah was secretly smelling used tampons, and so forth. All were heralded as 'shockingly brilliant', 'stunning' and 'questioning our established values' at the time. Quite frankly, I think all are sick {bleep}s who should be regarded as such. Mind, I do not object to people being gay, if it makes them happy, fine, bless them, but don't force me to read about their sexual fantasies, because that will have me running for the nearest toilet at an appreciable fraction of the speed of light.
All in all, I don't think the decision to ban the book was a good one. Students need to learn about the utter nonsense which goes on in other people's minds, and learn how to guard themselves against it. And if the literature teacher is worth her salary, she would accept the excuse of a student who did not read the book on grounds it was utter crap, provided said student could bolster his arguments. That is the main reason you are made to read: saying that you dislike or like something is one thing, but can you say why?
