I have no problem with those who are not certified in mask use using them. I do feel for them for the risks to their health they are taking. But those of us who are certified have ethical responsibilities that those who do not have the certification lack. Being trained in various safety issues is a burden the untrained can not imagine. Ignorance is bliss. But to be honest, I doubt I would wear one anyway. I can scarcely breath without a mask as it is.
