if you're going to take the stance that biological sex isn't real and that gender isn't binary, then maybe don't turn around and lecture me on how cis and trans are rigidly defined terms and that cis people can't be non-binary

I identify as non-binary because I reject the gender binary, because I refuse to be confined to any one (binary) gender, and because my presentation does not always match my assigned gender.

however, I feel very little body dysphoria and I have no plans to pursue any sort of medical transition. so to call myself trans feels disingenuous. I can easily pass as cis if I want to. I will never face the kind of discrimination that, say, a trans woman might face. to call myself trans would be to erase the experiences of trans people who actually transition, and their unique hardships
