I don't know where you've these ideas, Daniel, but you paint with a wide brush. Why not this for painting a group whom the writer labels and places into a neat little box he or she can understand- requires no thinking: Many writers think they actually know what they're writing about and try to avoid click-bait titles and don't research what they're writing before putting it out for the world to see. Others don't.
And this article belongs where? Under satire, I suppose because there is no way an honest person can say these things, but a Republican troll or someone who wants to attack the Democratic Party from the inside can.
As in, "They eat their own".
