It’s not an idiotic suggestion and it’s not to make other people feel good. If you have allergies that doesnt mean you can’t also be an asymptomatic carrier of the virus. So, if your allergies cause you to cough or sneeze you could still expose others to a virus you didn’t know you were carrying. Studies have even shown that there’s been an enormously high rate of infection linked to asymptomatic carriers based on antibody testing. This isn’t ideal for anyone but to call it “idiotic” because it inconveniences you is incredibly selfish.
