To each their own but I'm pretty glad masks are on their way out. I wore one when I had to during the pandemic and I'm quite happy that I didn't have to wear one to any of the conferences I've been to since the pandemic ended.
I am astounded that four years in we still need to explain that a) masks are effective in stopping community transmission b) masks worn by the source are more effective or, in other words, your mask protects me while my mask protects you. How is this new?
No, your stance is absolutely selfish -- not uncommon of course, but it is selfish.
He isn’t any more selfish than you are, traveling to a crowded conference while living with an immuno-compromised person, and on top of that expecting people to bend over to your requirements.
