Your argument is invalid, and falls short on several levels.
One: Unfair deals are unfair. - tautology, you cannot have a fair unfair deal. The logic of your whole argument is flawed from the beginning.
Two: A student..... with pain. - This is not even an argument, it is an appeal to emotion I.E. a "think of the children" argument that is used when there is little support for a logical argument.
Except that's not how logic, morality, law and fairness works. Continue to be obtuse if you wish, but you're not persuading anyone with stupidity.
See, thats exactly how logic works.
1: A person is responsible for themselves if they are not required to do something,and especially so if they know it is a dangerous activity, but they do it anyways.
2: Said person gets injured while doing that something.
3: Therefore, said person is responsible for their own injury.
The logic is 100% sound, you may disagree with principle one, but that does not make the logic unsound.
Point A:) Perhaps you should go back to Philosophy 101, and maybe ethics, yourself before you go attacking someone else, which in and of itself is another sign of not having a solid argument, before you go around telling people how logic works.
Point B:) There is no such thing as "fairness", it is a man made construct that can never be realised since there will never be a consensus as to what is truly "fair". Every single attempt to come up with a scheme that is "fair" will have to affect some portion of the population it is being applied to negatively and will be viewed as unfair, thusly negating the whole principle.
