When someone making a technical presentation states "we believe that...," I typically point out that beliefs are factually irrelevant and am only interested in the data that support or refute them.
The current fad of "identification" is right out of South Park, and is subject to Poe's Law. I suppose I could identify as a lesbian trapped in a man's body, but my lesbian pals don't seem to care that I'm a breeder. Actually, one pointed out that she found being called "sir" annoying, but not that big of a deal.
Anyhow, beliefs are fundamentally delusional. If they happen to coincide with reality, it is largely happenstance.
