I fully agree with the substance of your piece. I also think that I understand your purpose in the repetitious use of the word 'fucking'. However, your point could have been as well, if not better, made without the resort to such a device.
A more concise and incisive approach may well have been far more memorable & influential. Unfortunately, the very minds that most need to take heed of what has caused your outrage will have stopped reading by the end of the first paragraph.
Those minds, as you have pointed out, are so trapped in conditioned hypocrisy and narrow thinking that they will never push through their own preconceptions to investigate another view nor consider that their own may be misguided. Indeed, as you mention, they fail to see that their very behaviour, i.e. censorship, only increases the appetite of others for what they seek to deny.
Whilst working as a teacher librarian, I once had an angry parent burst into the library, shouting out my name and cursing me. I managed to calm him enough that we could sit down and I could listen to why he was so enraged.
His daughter of about 8 years old had taken home a picture book from the library and he had seen her reading it. The books was by Raymond Briggs, a brilliant picture book author with a strong sense of the incongruity of life and institutions and governments. This particular book was illustrated in cartoon format rather than with full page pictures. Speech bubbles were used to show the dialouge. Its title was Fungus the Bogeyman.
What infuriated the man was just one cartoon image in which the speech bubble simply had the words: Expletive deleted!
Fortunately, I did manage to calm this parent down but my point is that those on the school board that you mention are just as irrational as the parent in my anecdote and, quite probably, just as well intentioned. They simply miss the point for they are preoccupied with the needle in the haystack rather than the haystack itself.
We are all conditioned to one extent or another, most of us extremely so. Our schooling is not about education but about socialisation. The result is that we are taught to expect and absorb answers rather than to ask questions. That process is akin to putting blinkers on a horse - it may protect from distraction and allow one to fit into the traffic (social environment) more easily but it hides or obscures the greater reality or what is commonly known as "the bigger picture".
To change this, one has to speak in the language that the blinkered can understand and accept. :-)
