Let me see if I understand the whole issue. Data (speculations based on data) suggest that there was no Cambrian explosion after all, other data (such as fossils) do not (yet) support this idea. So there appears to be a conflict. The fossil data might be complete and the speculations are wrong or the fossil data is incomplete and the speculations are right. Both positions are based on a scientific approach, unlike the purple monsters you alluded to.

True; but not for Precambrian complex animal forms, and therein lies the rub.
