Wrong. Most evolutionists are theists. Indeed most evolutionists, being theists, are creationists (just not, of course, in the antievolution/antigeology/etc sense of the term).
You talk about "validating the polarization of thought process". Well, you just did it.
Granted we all use the shorthand "creationist" here when we actually mean "antievolutionary creationist". But here you're extending this usage beyond the point where that limited and specific meaning is understood from context, and instead implying a universal and unexceptioned dichotomy between "creationists" and "evolutionists".
Properly speaking a "creationist" is anyone who accepts a (usually theological) doctrine of creation. Such a person may or may not reject evolution, an ancient earth, and such, and may hold any of a number of differing views regarding the relationship between science and religion.
I just got home from a 16 hr day and my mind just couldn't unscramble all those words.
I'll try to remember to come back here Saturday.
