"Complicated subject matters are not so easily explained in simple lay terms"
Verbosity and intelligence are not interchangeable. Abusing a thesaurus to cover up the intellectual void behind your words is the cheapest trick of the demagogue. Your first paragraph, for example, boils down to:
"I want to imply that I'm saying something clever and you don't understand it because you're stupid. Also I don't want you to actually understand what I'm saying, so I'm using big words to make you think it's important."
