I don't disagree with this: "there is a nature of an entity with respect to generic features shared with other entities -- but that doesn't rule out the rest of the entity's nature." I never claimed that the nature of something rules out the rest of the entity's being or identity. But (I hold that) the nature of something focuses on what it must be to be the kind of entity it is, which excludes from consideration the details or accidents.
That looks to be subscribing to a doctrine of natural kinds, which I believe Rand would have regarded as a variant of conceptual realism and something she would not have accepted. As for myself, I don't think I accept it, either. What is natural to entities is not their being of a "kind," but of having certain specific characteristics -- which necessarily means not just some isolated or singled-out (singling-out requiring a conscious entity) characteristics, but all of them.
You say that you didn't caim that the nature of something rules out the rest of the entity's being or identity. I didn't make that claim; I said that your position amounts to ruling out the rest of the entity's nature, although I've also pointed out that I use "identity" and "nature" interchangeably, and so would have Rand. (There was some contention here about what Rand's position was, yes?)
To reiterate: The nature of something is just what an entity is. Here, we are still in the realm of metaphysics, and not of epistemology, where we can make sense of talk of such ideas as kinds and essences. "Nature" is a concept applicable to metaphysics. The nature, i.e., the identity, i.e, the what of an entity, is the sum of its characteristics. To be an entity of a particular nature is merely to be what it is, not to be an entity regarded as a member of some class or kind.
Edit: Clarifying this last point: it's not the regarding an entity in a certain way that confers upon an entity its nature. That's what's effectively being claimed happens, though, when one equates an entity's nature with its essential characteristics. (I would have said "the entity's essence," but strictly speaking they don't have essences like some metaphysical aspect or feature of them. There is no essence "in" the entity. But they do have characteristics that are essential to them being objectively regarded and classified in certain ways. That's the unpacking of the phrase "essential characteristics.")
