Mandatory sentencing laws take the judgement out of justice. Today's scales of justice weigh vengeance and revenge against each other. What's so funny about peace, love, and understanding, anyway. All of our rights are mere vapors, and yes you can be coerced into undergoing medical treatment. A family member can go to court to have you ruled incompetent and force you into treatment.
Rights ARE absolute, by definition.
That is not to say that the exercise of rights may be allowed to be unregulated. By nature, a right may not be conferred or removed, as can a privelege. I think you have every right to refuse any treatment, for any disease. It is your body after all. If the disease affects others, then I would be quite happy to move, or have a lethal injection.
