The "level" at which they attack
They are all rabble-rousers, publishing BS to elicit emotional reactions from people.
But some of these rabble-rousers work at a lower level, some work at a higher level.
Some just want to form a lynch mob, stage protests, or maybe get angry support from a few dozen people.
Others want to bring down the whole sociopolicial system. Democracy.... or Capitalism. The crankiness seems to be proportional to their ambition.
I admit any analysis is a little murky, and since I'm not a political scientist I have a hard time differentiating the various categories of abstraction. Generally, I don't read these people's articles. I find them distasteful.
