What's wrong with people? can be asked from the Christian and creationist point of view too, but such things get answered by those who have the POWER to answer them according to their own opinions, not necessarily those who have the truth.
I'm trying to work out what you mean by that... You seem to be saying: From the Christian and creationist point of view, the question "What's wrong with (non-Christian, non-creationist) people?" gets answered by those who have the POWER to answer according to Christian/creationist opinions, not necessarily those who have the truth. Did I understand you right? If so, I'm inclined to agree with you.
Evolutionists think anything done in the biological sciences confirms evolution
Right - and this line of thinking is based on the fact that all available observations of real-world evidence point to this conclusion. For instance, the particular details of DNA evidence that serve to establish paternity are of the same type, with the same truth value, as the details that establish the fact that all primates have a common ancestor, as do all mammals, as do all tetrapods. In order to deny the latter relations, you also need to deny the evidence used to establish paternity across a single generation.
... but most of it describes only microevolution which creationists regard as normal variation through built-in alleles.
And the existence of ring species is something that causes creationists to abandon or deny logical, evidence-based thinking.
... they refuse to recognize that depleted genetic diversity is the necessary end result of evolutionary processes...
And that's because it would be a serious mistake, going against all observation, to assert that "depleted genetic diversity is the necessary end result of evolutionary processes." That's not something that can be "recognized", because that isn't what the evidence demonstrates.
