Does wearing a mask help prevent the coronavirus? Probably, but it's hardly the most important precaution one can take.
But here's what I do know - wearing a mask helps prevent my Dem governor from shutting down my business. It's the sort of virtue signaling that liberals like and respond to. And when it's liberals who hold the power to determine whether we can work to earn a living, then yeah, if you won't wear a mask for yourself, then do it for your neighbor stuck in this hell with you.
