Germ theory is real and we need to be mindful that Covid-19, HPAI & other communicable diseases are not going away simply because 'the popular people' are no longer wearing masks.
I understand how persuasive "online influencers" may be but no amount of popularity can alter the laws of reality. These viruses are still spreading, still mutating & still causing people to get sick (some seriously) or even die.
If our society is not going to keep up with their vaccinations, then our society should not be surprised when individuals from that society performs additional protective measures in an effort to avoid these harmful infections such as wearing masks in public.
I certainly hope that there is a day when science is advanced enough (and our social attitudes are advanced enough) for when masking is no longer a necessity; That day, unfortunately, has not arrived. Hopefully, it arrives before the next pandemic may occur.
