OP, I have female friends who are simply not interested in it . They think it is a non-issue and if work requires them to put pronouns in their emails, then they will. Because it is a non-issue.
If you scratch the surface, you might find that she doesn't believe that anyone can change sex and that a male person should be in any female single sex spaces.
Or, she could be doing this because she fully believes what she has read or has been told and wants to be seen as supportive.
I think that the UK is ahead of quite a few countries. It is certainly a few years ahead of Australia and unfortunately there is a great deal to be done there to reverse the leglislative damage, but it is still not widely discussed or understood. The USA seems to have woken up but it is still behind the UK in the discussion.
I say were seem ahead because the discussion has matured here, and because we have had court cases and instances where the discussion about pronouns has been important. This past few weeks, I have seen more and more people declare that they will not use requested pronouns any more. Because they feel that it has led to people such as Dr Upton now twisting language to define Upton's self as 'biologically female'.
I have said for a while now that the demand for using pronouns is a demand to show compliance to someone's philosophical belief. And what other philosophical belief has society demanded that we all support with dictated language. Can you think of any? So, why is this belief different? Because it was initially informed as a being something that was a diagnosed medical condition.
And I think a few people genuinely believed that people can change sex. But it was never true. Sex is simply not something that changes by castrating a man and giving him oestrogen.
However, over the past years it has even shown that the only thing in common that people with transgender identities have is their belief. Their philosophical belief that they are the opposite sex or no sex or some other of the 130+ genders.
The question really does remain, what other group does society comply with such demands to change the established language conventions to suit that group's belief? Why is this one so special?
(Of course, it is because we have been emotionally manipulated to believe also that this is the most vulnerable and marginalised group on earth.)
