There is that insistence on freedom before all other values which you deny is part of your argument here...
I have categorically not insisted on freedom before all other values. I have asserted that freedom can be reasonably restricted to keep the child safe. Logically, therefore, the safety of the child is my first priority. No?
You need to explain the unreasonableness of this 'imprisonment' to me. In your answer, please discuss why the teenager can't just stay in school in the first place. Why can't people just stay in school at close quarters with others, inhaling and exhaling the same air, using the same loos, singing together in a choir, knocking into each other playing hockey, etc?
I don’t need to explain why keeping a person confined to one room is wrong. If you can’t see why it’s wrong, you clearly have some alarming tendencies.
Your alternative of allowing the possibly infected teenager the full run of the house while those feeling nervous about contracting a potentially deadly virus should stay in their rooms is unreasonable to the point of being bonkers.
So it is not incumbent on people to do what they can to protect themselves before confining young dependents? Really? And you think I am the “bonkers” one?
So I will ask you again: what should happen if the child (quite reasonably, IMO) says they will follow the law and remain in the house, but they are not prepared to be confined to their room, and would prefer a space-sharing arrangement or for the frightened person to self-isolate instead?
