The top reply to pg in that thread is dcurtis, and should maybe give
everyone concerned a bit of a pause.
EDIT- dcurtis says Aaron is egotistical in his blog posts, as a comment on a post that asks what Aaron has ever done. The parallel to recent threads about dcurtis is eerie, to be honest. It's jarring enough that it should make everyone on all sides of that issue take a step back and get some perspective.
As pg says in that thread, egotism is a common flaw in bright youths. Perhaps some...not tolerance exactly, as guidance away from the flaw is a reasonable response, but maybe a realization that it's to be expected. And in the big picture, maybe it shouldn't really count much against them anyway.
