Consider the type of male behaviour you claim to abhor, and take a look at yourselves.
Must confess I am exceedingly puzzled at this. We have none of us here on this thread been aggressive, violent, entitled, arrogant, superior, contemptuous or patronising. Those behaviours I abhor. They are not male behaviours alone, females are well capable of all of these, but they are very frequently male behaviours, it's true.
We have been knowledgeable, articulate, determined and assertive. Which are female behaviours as much as the above, but more often than not assertiveness is thought of as a masculine trait, of course.
The only thing we have not done is acquiesce to the demands of a male that we forego our rights and submit to the various mechanisms employed to manipulate us into giving in after we said no.
Saying no to a male. That's our crime here, isn't it?
And the thing RobinMoiraWhite likely will never understand is that I too would have been accepting, sympathetic and respectful had my colleague Robin come back as Robin Moira. I couldn't care less what opposite-sex stereotypes a colleague chooses to externalise or internalise, as long as they fall within the boundaries of what is accepted behaviour and apparel in the workplace.
I wouldn't have complained at finding Robin Moira in my toilets either. I'd have been upset and uncomfortable, depending on the circumstances I might have felt frightened, I definitely would have found it inappropriate and profoundly unfair to lose my right to privacy and dignity. I would have felt exceedingly angry and disappointed that I mattered so little that no one asked my consent.
And as soon as I realised that this was now a permanent arrangement, I would have found a place where Robin Moira didn't go.
Occasionally, when these situations involve a stranger, I quietly leave, walking straight back out if possible. And when I become aware that a previously female-only facility has become mixed-sex without structural changes, like my local Debenhams changing rooms, I exclude myself entirely.
Any male who identifies as trans in this situation would be completely ignorant of my true feelings. As Robin clearly is.
