Memes oversimplify the issues at hand and do not allow for important nuances.I’ve seen that meme too.
the point of the masks is that it re-directs what you breathe out from traveling up to 13 feet from you with no mask, to a more manageable 3-4 feet. Couple that with social distancing, and you begin to reduce the chances of spreading in public spaces. It’s simple, but many have made it political, and thus, more complicated. Don’t get your news from memes.
