I can imagine! There was a time I had mismatched ideas some saying F others saying M and I can guess it is something like that with the added difficulty that many things you do don't even have the correct field to allow an X, but still require the field for completion.

I can imagine it could also make voting more difficult. Poll workers tend to be older as well so I'm sure many get very confused and don't know what to do about it. I would also imagine it makes police interactions more stressful, as we know cops are horribly transphobic and because only non binary trans people get the X it sort of prevents you from being stealth for your safety even in that moment.
