Here’s one definition of identity:
The quality or condition of being the same in substance, composition, nature, properties, or in particular qualities under consideration; absolute or essential sameness; oneness.
Oxford English Dictionary
However the way we more commonly see (and hear) the word identity is in the context of culture and politics. Here’s another definition:
Who or what a person or thing is; a distinct impression of a single person or thing presented to or perceived by others; a set of characteristics or a description that distinguishes a person or thing from others.
Oxford English Dictionary
Outside of mathematics and philosophy—where I am thinking about identity in reference to being indentical and being equality—I don’t know what identity means (and even within these domains I only understand the word “identity” about as well as I understand it’s cousin word “causality”).
So, for me, the word and concept of identity is principally related to the metaphysical concept of being and secondarily related to the epistemological concept of definition—complicated stuff.
Perhaps that’s why I have a hard time discussing my identity?
