Those of us trained or literate in the sciences seem to have trouble following why Creationists-by-Argument (as opposed to Creationists_by-Faith, with whom I have no argument and for whom I have much respect) cannot follow what is to us fairly simple and clear reasoning.
I think it is because they (Creationists-by-Argument) are trying to use science to 'prove' their religious theory of creation (in part by attempting to disprove evolution). They are trying to drape their religious belief in the robes of science. I think they are doing this to try to proselytize their belief.
Creationists_by-Faith accept that their belief is an article of faith and they are not trying to use science to proselytize their faith. They are not attacking science. I too respect Creationists_by-Faith. They understand the separation between science and religion.
Creationists-by-Argument are not interested in simple and clear reasoning. IMO, they are proselytizing religious fanatics.
I like your distinction between faith and argument. I think there are many warnings in the Bible, both Old and New Testamants, against trying to reach God through understanding.
When I see people arguing about hidden messages, Bible codes, 128 bit encryption (I'm not making this up), obscure translations of particular words -- I want to throw up my hands and say, Stop! Haven't any of these people ever read the Bible with their hearts? Do they really believe that only people who chant the right words are eligible for membership?

I agree, at least in part. Some are clearly charletans, others may be so emotionally (not religiously) attached to their position that they need to blind themselves, and some may just not "get" it. And I am troubled by all proselytizing by pressure...either political or violent.
