Most Stupidity.
Most stupidity - of word or deed - is best left responded to with a grunt or eye-roll at most - but otherwise ignored.
To do more is to draw attention to and breathe life into what would otherwise wither and die from neglect.
The problem is if the stupidity is repeated, ignored, repeated, ignored - then it will more likely gain more stupid followers.
Fools who seek the attention of the bored, idle, and media that comes from leaping about in the fringes and extremes.
Left unaddressed, eventually someone will form a ‘community’ or acronym or political party to advance the stupidity.
