Very funny analogy, but it is just that, an analogy. Intuitively, yes, it would appear obvious that masks would prevent spread. However, as I said, scientific opinion is mixed, and even the CDC reversed themselves, without publishing any data that explains how they came to that decision. My point is that a mask *will not* prevent one from getting infected, so we should not become overconfident.
False. *May not* is considerably more accurate. That's not the sole purpose of masks, anyway. Surgical masks, for example, aren't intended to protect the wearer so much as they're intended for the wearer to keep their germs to themselves.
