My own experience
Is that most--not all, but most--people who feel the need to wrap their ideas in a load of excess verbal crap are trying to slide something past you.
When the ideas are distilled down to their basics, the problems become obvious.
Honest people at all levels of intellectual discussion won't mind rewording or modifying their concept to reach different audiences, and won't mind filling in the blanks where necessary.
Note that obscuring the truth isn't always about complexity. If you look at real propaganda, you notice how little of it actually SAYS anything.
