Masks probably wont stop you from getting the virus by it self there are other factors also such as hygiene and social distancing.
To blast someone for wearing one is what’s the stupid part.
If you feel some what safer wearing one go ahead and wear one. My wife and I do we have family members with medical problems.
You will at least have a little protection.
Let’s say there are two people one with COVID and doesn’t have symptoms and the other that doesn’t have COVID nether wear masks. the possibility of the uninflected person is greater then if he wore one. And same if the other person was the only one to wear one.
If both wore a mask it would cut the chances even more because it would help cut the aerosol spray from breathing, talking, coughing, and sneezing.
