Exactly. Idiocy by definition is usually not a voluntary thing, it's more often culturally acquired (brainwashing) or biological (neural interconnection and synapse density).
Extremism is always an insult used by those who are proud of their mediocrity.
And yeah, I'm not taking it personally because it's the first category in this case, that leads to the second, which is one of the ways in which this frustration at stupidity is turned into an excuse to tittilate yourself with other people's discomfort, and thus the mark of a bully.
When I encounter bully behaviour IRL these days, I'm either, get the fuck away from the clique that will slavishly defend this dominator, or if they are the new one, sock them in the eye to remind them that we aren't everyday internet people here.
