No one is going around berating people wearing masks. Most people will leave you alone if you do the same. The whole world shouldn't engage in maintaining a minimum distance from each other at all times because of the mere possibility of a small fraction of a percent of the population actually being present to benefit. You should advocate for frivolous mask wearing to be stopped to draw attention to those who do have these conditions. For whatever good it would do them. Either way they still should not be about in public. Doesn't matter that it isn't going to happen.
