It is no more hollow than Darwinism. Darwinists start with the assumption that everything evolved from a common ancestor, thus everything evolved despite that we don't know (nor can we know) every step, and they fit all the data into this model. As in with whale evolution, they see the modern day whale, purport that it evolved, and then they go out and try to find the basal species. So when they find something that looks archaic (likepakicetus or ambulocetus) they assume that this group of organisms eventually evolved into whales today. Similarly, our assumption is that God created distinct kinds that diversified overtime via adaptation. Despite that we can't know where every line is, we take the evidence (as do you) and see how it works in a creationist model.
This definition is called evilution. Under this definition the idea of kinds become a tautology, so no wonder few creationists are aware of this definition. But I would think that your encounters with YECs are skewed, giving the stereotype of dumb rednecks that don't know how to use a computer. There are many YECs that are well educated, productive members of society, and understand the darwinist paradigm more than you (and practically every evo here) would care to admit.
