@OldCrone thank you. That is exactly what it is. I did feel that as the thread went on that people had lost sight of the wood for the trees 
I do not know the woman but, from what she says, she is no small fry either:
I previously had worked in public services with decades of experience in children's social care and education. Questions of equalities and rights were matters of which I had long and well-respected experience in Scotland, the UK and Europe.
We do not know whether the Charity was influenced in its approach by any pressure, or any fear of impact on funding if it did not deal harshly with her "transgression".
What we DO know is TRAs have not been slow in the past to lobby charities aggressively and threaten funding e.g. pressuring venues booked for meetings about the GRA Consultation. Presumably the Charity was aware of how things might pan out if it did not react decisively?
We already know that someone connected with the Charity in some way was sufficiently affronted to report her words as a "contravening Equalities Legislation", so there was some "TRA-type" pressure within or close to the organisation.
We also know how aggressively TRAs can threaten, smear and harass individuals, women in particular, who voice legitimate concerns about both Self-ID and "watchful waiting" vs "affirmation".
I would not like to have been in her shoes, unsupported and isolated in that workplace.
To speak out publicly now, rather than hide away and lick her wounds, strikes me as courageous. She does not need to put her head over the parapet again and the impact on her personally and in terms of future employability is hardly likely to be positive.
I hope that if she needs support that she can be sure of finding it here
and thank you too @Clitherow
