People who are dehumanized and unidentifiable do things that they wouldn't normally do -- cruel things such as preventing a person on their deathbed from receiving a touch -- much less a final kiss -- from a loved one or taking away a year (now going on two years) of precious childhood from our kids or demanding -- demanding! -- that a stranger obey the masker's demands no matter how irrational ... even inhumane things no matter how severe or irrational. There are myriad examples of this behavior by maskers over the past year and a half. This behavior is increased by orders of magnitude when the masker is already in a perpetually frightened and ignorant state as most are.
Masking, fear and ignorance together represent a lethal threat to a free society.
This has sexual connotations as well. In the S&M world, the dominant will usually have his/her submissive don a mask in public - in order to establish the pecking order in a master/slave relationship.
