Maybe it's your simplicity (lack of duplicity) that brings many to erroneously conclude you are dumb.
That's a very intelligent way of breaking down the culture and yes, I agree with you. We live by the KISS "Keep it simple, stupid" mantra for most aspects of our lives.
I'll have to check out that book, if you can recall the name of your favorite of them I would love to know.
The Gospel Singer was the first that I read, and I believe it was one of his earliest novels. It was good enough to put me on a Crews binge. Car (I think) was another, in which a redneck eats a car, for real. And A Feast of Snakes was really good. He wrote one that I enjoyed about a body builder, can't remember the title of that one.
