I would agree, and I would also add that many of the Creationist leaders have the same view of their cause as political extremists do; anything that forwards the cause is (by definition) true, and anything that thwarts the cause is (by definition) false.
The only time the "party line" is changed is when it is no longer an effective argument to convert the uneducated masses, not when it is shown to be incorrect.
They don't actually see it as incorrect if it supports their preferred world view, regardless of the evidence.
I would also contend that Creationists, almost across the board, utterly lack the ability to intellectually step outside of their own convictions and argument in order to hypothetically take another position. Consequently, they often lack any kind of knowledge or education of that which they vehemently argue against.
