The issue is that people do 'get' pronouns, & are not prepared to mangle the English language.
There are compelling arguments as to why may be important on a subliminal/safety critical level. I'm no scientist, but training our brains to accept something our eyes know on some level isn't the case, is potentially overriding the safety reflexes many women employ so automatically they're not even necessarily conscious of doing so.
I understand those arguments, and also comprehend that no matter what concessions people give they are never enough (cf ''Meet me halfway said the unreasonable man...'). But as to how others choose to refer to themselves, I will respect whatever pronouns they ask me to use.
My hill to die on is when the same constraints are imposed on my rights to self-definition. I ain't no 'swimming vagina-haver'. I don't want to announce 'my' pronouns - that's if I can be said to be in possession of them - given the discrimination women routinely face in the workplace when they draw attention to my sex. When it comes to that issue: 'cis' I do not accept. I've spent most of my adult life fighting regressive gender stereotypes: the hell am I going to adopt them now because it makes others feel more 'comfortable' at my expense.
The bigger issue is that people can avoid whoever they like, for whatever reason they like.
In some workplaces this isn't possible; recollect this document is geared towards university staff, not students. What I would by no means do is permit incendiary discussion of a particularly toxic issue within my lecture space. And within that space, what I say goes. It's negotiable on the basis that such discussions can be too incendiary and potentially distressing for trans students. Nor do I believe only giving space to an accepted party line is conducive for productive discussion.
If I am 'avoidant' of somebody because we have very different opinions, will inevitably clash & I'd rather skip the aggro, that's a perfectly reasonable position.
I wish it were. In this context, even not wearing a rainbow lanyard or announcing pronouns could be seen to be avoidance, as could walking out of toileting facilities by anyone uncomfortable with sharing spaces with the opposite sex (irrespective of gender).
I'm aware a lot more of these documents are in the process of being drafted. It certainly isn't going to affect just Newcastle and Edinburgh.
