I agree. But that describes the average creationist-follower. I was talking about the kind of high-profile creationists who work full-time at promoting their ideas that tend to be mentioned on Pharyngula. From the descriptions there of what they say and do, I have gained the impression that they often lie; e.g., by presenting an argument while ignoring and never answering the objections given at previous debates; or by saying unsupported things like "evolution is the subject of a controversy in science".

I don't live in or near the US, and all I know about US-specific creationists I learned from anti-creationist sources like Pharyngula, Dawkins' books, etc. So taking them as examples, I'm disproportionately aware of the highest-profile creationists. But they at least do certainly lie.
