Of course, Ned, you understand that Creationism, in its broadest sense, is a basic tenent of Christianity.
You lost the context of this discussion and should not be capitalizing "Creationism". There is nowhere here where that means anything other than a literal meaning of Genesis and the "creation" of living forms. It is NOT anywhere here used to refer to the simple belief that there is a sentient "creator" that acts through the natural laws we see and may be taken as "kicking off" the big bang or setting up conditions in which it would occur.
This second and, here, NEW use of the word "creationism" is, of course, a tenant of Christianity. But Creationism, as it has been used all along here is clearly NOT a tenant of Christianity.
It is careless or even disingenuous of you to mix the meanings, don't you think?
Now with that clarified, why should there be a problem?
