There are always going to be leaks and there will never be 100% protection and there will never be "zero covid". The entire mask argument is irrelevant and only serves to distract and divide. We should have said from the very beginning that people should stay home if they don't want to catch the virus. And if you want to go out, it's at your own risk. It was that simple. Instead we have tripped over ourselves for 2 years trying to come up with ways to curb the virus without having any impact whatsoever, destroying and dividing the fabric of our society along the way.
