This is a social media and/or message board personality who repeats information from other sources while acting as if they are liberating your ignorance with their brilliant intellect. The sources they rep are often total shit, and they display a
pathetic understanding of the concept of critical reasoning.
One particular example would be the modern evangelical conspiracy theorist, who repeats information from preposterously unreliable sources, adds no new perspective, and berates any detractors with parrot phrases such as
sheeple, wake up, or best of all do your research. It does also apply to thoughtless fanatics of any persuasion, political, religious,
sports,
music, whatever - basically an arrogant recycler of information without credibility - often causing the opposite of their own intent by being so annoying that no
one wants to consider the content of their message.
I tried to tell this fucking parrot that the site he
always links to is only there to sell
books and advertising, and that their
biased perspective was not logical and in fact impinged upon legitimate concerns, but instead of considering what I was saying he just told me to wake up. Or - I wish these parrots would keep their mouths shut, because all they seem to be good for is feeding trolls.
