Is it unusual in this day and age that I don't "identify" as anyone or anything?

I just don't. To me it's meaningless, and rather pointless, to "identify" (i.e. separate oneself into a tiny in-group from the rest of mankind).
People change over time. A lot, as it turns out. I'm not the same person I was ten years ago, or even just ten months ago, so why would anyone think it to be a good idea to become overly attached to a label?
I'm just me. That is who I "identify" as. ☺
