I'm not telling people not to cruise.
If you're telling me "it won't happen, nadda, isn't going to happen" or in your case you literally said you won't cruise is masks came back for passengers I and other posters are in a practical sense saying it how it is. I have no vested interest in you or anyone else going on a cruise, but if you're going to take a stance that you won't cruise if xyz comes back and there's literally cruises where this has happen I believe any one would realistically expect to have someone say cruising may not be for you. Just like it was for any destination that had protocols people were concerned about from testing to vaccination to quarantines/isolation. The advice was very standardized and not personal at all.
I'm sorry you're upset at this advice, I just hope it doesn't happen to you, I can only imagine how upsetting that would be to be on a cruise and have it happen
