I think you read much more into this than I wrote, in fact I have no idea what exactly in my comment you find terrifying.

Banning access to airplanes is already being done in cases where the airline decides a passenger isn't worth the trouble, just like a restaurant owner can ban people. Using a no-fly list is too much, and wouldn't do more than that either way.

Anti-vaxxers/Covid deniers have physically assaulted and sometimes even killed bystanders and it's not far-fetched to assume they don't take safety of other community members as seriously. Why would I want to share a plane with such people?

Some extremists that are also supposedly unvaccinated have done that.

Lumping everyone together under one insulting label and then judging them by the worst apples leaves you with a skewed image.

I would say it is extremely far-fetched. Of the unvaccinated people that I know, nobody is aggressive or violent or would ever engage in behavior that is risking the safety of other passengers.

Punishing them for what some extremists have done is neither fair nor lawful.

Would you prefer to share your plane with a psychopath who happens to be vaccinated or a lovely person that happens to be unvaccinated?
