Jenny there are many ways in which this could be harmful to trans and non trans people
Trans people might not be ready to be outed
Women (especially women such as myself) with a title of Dr and an androgynous name would immediately be identified as female and therefore discriminated against. Links can be provided.
But for me the biggie is that I don't believe in gender identity and I don't want a tagline which implies I do.
My sex and any gender reassignment are protected characteristics. Why should I have to declare them?
I don't believe in any god either, but imagine if I were requested to put in my email signature 'i believe that xx God is our one/many true saviour', and asked to fill in with a God and multiplicity which suited me?
None fit! And it's noone else's business, I don't believe in religion, and I don't want to have to put something in there.
To me this is similar - my sex / gender are NOT RELEVANT to my ability to do my job. The former is a protected characteristic, the latter is IMO a made up bit of nonsense, so why on earth should I put something to please a group I am not part of?
I'm not going to tell anyone else their gender / religion is nonsense or wrong, but I don't want to have to pretend I have one.
