Think about this for a second.
Without widespread, most-often mandated mask-wearing, most Americans wouldn't even be thinking about -- much less be living in a constant state of fear, distrust, depression and anger of -- this year's waning Chinese Flu. This would be "old news" and people would once again be going about their lives as they were just three months ago!
Masks are promoted to keep fear alive. That, and to engender a habit of submission to authority figures. Both are contrary to US citizenship.
