I haven't abandoned anything. I think you have lost track of who you are arguing with, and why!
I have consistently been arguing from this position. If you look at all of my contributions to this thread it has been from the position of disability.
I am immunocompromised. I have been assaulted for wearing a mask.
Banning me from wearing a mask means I am effectively banned from public transport, shops and the workplace. I have said this over and over and over.
As I have said, repeatedly, no one has made any credible suggestions about how "medical exemptions" to a face covering ban would work in practice. Saying medical exemptions are "up to lawmakers" is hardly a useful contribution, and is not reassuring to those of us that are raising concerns.
(I have also said that I don't like women being made to wear face coverings for religious reasons, but that the state forcing them to remove them is just as bad. But I am not going to get bogged down with that because (1) plenty other people are arguing that position, as I have also noted in previous posts, and (2) my main interest in this topic is my own ability to access services and the workplace.)
