The idea that if you're discussing a viewpoint or theory that is highly contentious or controversial, if you make it seem like it is much too complex for the average person to understand, and only comprehensible to a select few, enlightened individuals in a secret smart-person club (such as yourself, of course), by using a lot of jargon and esoteric references that only other
people in your very exclusive circle will
get, then it will fool the general public into thinking that it must obviously be correct because it's "complicated", and discourage anyone from questioning it (and also, jerk yourself off for being so smart).
Note: This does NOT apply to fields that actually are just extremely
difficult to understand and over most
people's heads (rocket science, quantum
physics, nuclear engineering, etc.). This is when you take something that really isn't all that complicated, and act like it is, to give it an
air of legitimacy.
When radical communists discuss Marxist theory online, and go on about
stuff like "praxis" and the finer points of Bolshevism vs. Trotskyism and other shit that nobody who isn't glued to a
computer 24/7 has even heard of or gives a flying fuck about, they are engaging in obscurantism.
