Yes. If I wear an N95 mask with exhalation bypass (The most common type here in Canada, due to our freezing weather) — I’m not protecting anyone else, at all. As for protecting myself, if someone infected sneezes in my proximity, I’m stopping the large particles, but inhaling about 5% of the billions of small water droplets in the air around me. Remember, if you can smell it, you’re breathing it.

So, virtue signaling. And, deluding the elderly and those w/ comorbidities that you are caring for them and that they are “safer”, neither of which is true.

As I said - if you are at risk, you should be wearing a HEPA filter and sealed eyewear.
