The clear distinction is the absolute unwillingness to listen logic without screaming what-a-about conspiracy A, or conspiracy B, or C. Or the classic "your just a socialist" inbetween talking about their social security and medicare benefits.
There's clearly a segment of the population that has the inability to compute simple logic without triggering a fight/flight/amygdala response.
I used to think education was the problem.
But I'm starting to think this inability to control their emotional response when hearing anything that conflicts with their "belief system" is the hack that various organizations leverage to build a cult-like following.
Edit: thanks for all the fanfare(sarcasm towards the downvotes), I think that it proves my point.
