Why bother to be any identity?
Your existence is an identity, but if you take on someone's referenced conception of an identity, then you are actually posing your extant identity behind this more contrived one, and you also become a speaking / mouthpiece for whomsoever wishes to herald the referenced identity for their purpose and interest.
It is always futile, as you - and this has already been elucidated countlessly elsewhere, but simply put - every humanly communicated reference of human conception is, by sheer instantiation, an incomplete, simplified estimation of neither what was intended, nor what was received, by whomsoever is being communicated to. So what is being communicated?
A range of amplitudinally expressed permutations of physical conception (even just visual abstraction is a materially-dependent construct) which exists at the moment of time, occurring during the negotiation of its conception (as occurring through all those bearing the capacity to conceive of it at varying degrees of influence, which might not correlate to the potential capacity to conceive of it).
So then it would seem that you have no ability to take control over the formulation of a human conception, but it's exactly the opposite. The only semantically accurate representation of your identity is your actual state of being, and it is perfectly evident/self-evident, requiring no further participation or resolution. In fact, by foregoing from attempting to fulfill one need to have its conception acknowledged, you strengthen the expression of your field of being into one which bears greater elegance and strength, which itself is communicated in its pure expression. There can be nothing greater than perfection, and no estimation is necessary as that which inevitably must occur in order to encode a communicable representation of it.
