I think the normal gate-keepers for the meaning of such terms would be the scientific community which eschews them. This naturally leaves a vacuum and uncertainty. A definition which is as clear as many other distinctions in science could be made, but its not being made because the gate-keepers don’t like the terms, even those like you who are fair-minded enough to know the extremes of what evolution is believed to be responsible for have significant differences.
In my favor because YEC is less credible than about any other position. But I wish biologists would adjudicate it. I sense that they don’t want to touch it though, because “its all evolution” and any attempt to put distinctions or parameters on it would give creationists a thread to cling to. I don’t see you being particularly threatened by that. Were there more like you perhaps we’d have that distinction better defined. And I think that could only help scientific progress in the field, whether creationists are right or evolutionists are right.
