oops....I was wrong about that.
Somewhat. Thompson's flag ideas were as follows. The Confederacy's version left out the "white" part that Thompson talks about. It is still based on Thompson's design, but it leaves out the "white" portion of the original design that Thompson meant to have stand for the white race.
Semantics, but leftists are not being completely "Honest" when they post images of the Confederate flag with Thompson's quote.
