To Mask or Not to Mask?

Surprisingly, it turns out that the “leaders” of the world who seek to compel the citizens of the world to wear masks whenever they are in any public space are acting in direct opposition to the scientific evidence.

Our wondrous, beloved leaders are therefore either ignorant of the fact that the hard science indicates that masks are completely ineffective barriers to viral infection or another motive lies behind this latest “medically backed authoritarian edict” currently engulfing the world.
