Define "Kind"

Is that really how you remember it? I mean, seriously?

It's just kind of funny, is all. The way it actually happened was like this - everybody agreed that allopatric speciation caused a reduction in diversity in both populations, as you've maintained. But it was repeatedly pointed out that this was not an obstacle for evolutionary theories because mutation was sufficient by itself to, over time, overcome the initial loss of diversity. And, indeed, this is borne out by both the fossil record and the genetic record, which describe an overarching tendancy of increasing diversity of living things.Edited by crashfrog, : No reason given.

I don't remember a single person who disagreed that the form of speciation you were referring to constituted a reduction in the diversity of both populations. Maybe that's just my memory, though. Ah, yes. Well, you wouldn't be a creationist if you were willing to admit that there might be aspects of the study of the natural world that would be beyond your expertise.
