Re: History repeating
Those cases have no relation to one another. However, if I try, I am not on your side. If your school mandated fountain pen and informed you that other methods of writing were going to result in a penalty, then you have some good options:
1. Write in fountain pen.
2. Argue that, although they're asking you to write in fountain pen in order to train you to have good handwriting with them, ballpoint pens are going to be common enough that you don't need that skill, and therefore their policy should be changed.
3. Argue that, although you were told to write in fountain pen for handwriting, this course is not related to handwriting and a different form should be acceptable, and therefore their policy should be changed.
And some bad ones:
4. Write in your preferred method without permission and without attempting to argue otherwise, then act surprised when they do what they said they would do.
5. After receiving your penalty, demand that they refrain from enforcing their clear rules, not because you're arguing the rules are unfair, but because you don't like the consequences.
If you want to try an option 2 or 3 argument on AI, you can. We'll all listen and decide whether we were wrong and AI use is more acceptable than we thought. So far, you haven't, and nor have this student or his parents. They've gone for option 5, and you've chosen option 6: make up irrelevant analogies and pretend they apply when they clearly don't and form a coherent 2/3 argument in favor of something.
