I’m not sure you and your opponents can agree on a definition of “fundamentalist”. I think “Christian creationist and biblical literalist” may have been intended. Both Meyer and Gauger have not been clear on this, but I infer that they are both some kind of old-earth creationist, and in my experience this invariably results from a need to affirm the truth of Genesis.
And of course creationists are good at cherry-picking, as when they take Behe’s and Denton’s critiques of “Darwinism” and reject or ignore their opinions on common descent. We even have a fine example of just that here on PS.
