it's a quarter of the way into the 21st century, and there's no longer any pitiful excuse for this level of piss poor hygiene. it's clear public indecency. it's degenerate. perverted. disgusting. intolerable. further, it masks a level of poor self-esteem. the clear psychological reason that a person would hide behind a mask of facial hair at this late a date in history is that they're embarrassed at having such an ugly face and need to hide it underneath a pile of dirt and filth because they can't let the world see them for what they are. this low self-esteem and poor self-worth is a clear symptom of a substantive mental health issue.
enforcement should be mostly about fines for public disgustingness and gross indecency to start, to send the message that secular western society doesn't accept this and won't tolerate it. access to mental health professionals to help them manage their mental illness and develop a sense of self-worth should be available.
repeat offenders should face jail time for repeatedly offending the public and repeatedly endangering public health.
