You'd select non binary, no?
There isn't the option to select that, though. You have to select "yes, I consider myself to be trans" (I don't) and then write in that non binary is how I describe my trans status. But equally I can't select "no, I don't consider myself to be trans" because they have defined trans (and by definition non trans) in a way that just makes no sense to me... Like saying "my chakra and my sex are the same" or "my chakra and my sex are not the same". I just don't know what a chakra is, how I know if I've got one, or if they are aligned or whatever. I accept some people are very in tune with their chakras (chakrae?) and feel they are important... but to me, it just doesn't chime.
I am actually very binary. I am 100% female because I am biologically female. I am 100% not male, for the same reason! But that is the case whatever I am doing or whatever I am wearing or however I am feeling. I suppose if anything on the trans spectrum I would be "agender" but that implies that I believe everyone normally has a gender, but I don't (cos I'm special). I'm prepared to go as far as saying that I accept some people believe they have a gender, but wouldn't want to say that is "normal" (as in most people think that).
Though if everyone is non binary, maybe we are all oppressed and victimised minorities and need all the extra help and support and positive discrimination we can get
