Your friend has self excluded. If I was excluded from a category intended for biological women I would wonder why I was being excluded. If the category was based on gender identity alone, then it was a mixed sex category all along.
Funnily enough, women aren't bothered when they are excluded from events aimed at trans people - because it's OK for such groups to have stuff exclusively for them, just like women can.
She has not self-excluded. She has used the term 'non-binary' for about twenty years, long before the CTT wrote their non-sensical definitions.
You are using an anachronism to justify stupidity.
