The point of mask mandates is conformance. The point of conformance is control.

Pol Pot forced people to conform, down to the wearing of certain clothing — exactly like today's governments forcing people to wear masks.

While scientifically speaking, neither do black clothes nor do masks do anything, socially they exist as a means to enforce conformity. 

Back then, those that wore Pol Pot's black clothing were government conformists. They submitted to the Communist party.  Those that didn't were executed and purged from society.

Today, those that wear the masks and take the vaccines are government conformists.  Those that don't are a threat to government control, thus consequently harassed and excluded from society.

The control freaks of today today are trying to mask the exact same ways and means that democidal Communist control freaks used in the last century.  "For your safety".  "For your own good".  "For the good of the people".

The more times change, the more the tricks stay the same.
