Don't be too magnanimous, MrJack.
Species by definition should be very imprecise designations, since the process of Darwinian evolution tinkers with ancestral forms to create new ones. Where it becomes its own form is a purely arbitrary distinction, and hot debate is what we expect from any attempt to make clear demarcations.
Kinds, on the other hand, were supposedly created separately. There should be no problem whatsoever differentiating between them.
