Seatbelts are also uncomfortable, but we've all gotten used to that.
I agree that masks should be worn whether one agrees if they're effective or not.
However, with that being said, I personally wouldn't compare the discomfort of having one's nose and mouth covered (sometimes for extensive amounts of times) to be the same uncomfortable as wearing a seat belt, which to most people causes minimal or no discomfort.
ETA: We should probably move this discussion to the Crown Heights thread and leave this as the BDE thread, which we hopefully won't add anymore names to.
