I agree with you that when used within the term "identity politics", the word "identity" is equivocated down to a small handful of inborn characteristics.
The true identity of a person is something mediated among the person's inborn characteristics, their mental and physical development, and their social setting (credit to Jordan Peterson for pointing out the last one).
We often have to attach labels--like "conservative" or even "black conservative"--to particular aspects of a person's identity to facilitate efficient discourse, but we should be cautious in how much accuracy we can ascribe to these labels in conveying information about the person's identity.
