"Wearing a mask in public doesn't necessarily prevent contracting a virus. There is no study out there that can really prove it one way or the other"
Again, ass backwards logic. Ordinary masks were never espoused to be particularly effective in preventing contraction of a virus; instead they are a means to mitigate the spread of virus from you to others....not 100%, but mitigating. N95 masks are fairly effective in protecting from contraction.
