For the record, there is a historical evidence for use of they as referring to a singular person. I have no issue with it being used for singular or plural. It has changed a few times over the centuries and that is just how language goes.
My concern is only that her and she are recognised by the majority as terms that, until recent madness, refer to a person who was born female. To shun a basic word that relates to being female isn't sending a great message to those confused about their identity and gender and who feel we can change it at will.
I am pretty sure I can say I am not alone in this fact, but I have plenty of things about my life I am not overly thrilled with, but you know what, that is life. I am sure there are people in far worse situations than I, who genuinely have sufferings and persecutions at far deeper and intense levels that I know nothing about. People fleeing for their lives, being tortured, being used as slaves and abused daily. The list is endless.
My comfort level regarding my health, sex, weight, marital status or place in society, is of little importance, when I consider others that have horrific pain, suffering and life or death situations to deal with, sometimes daily.
I grumble my pillow is too soft or my mattress is too hard, or my Chinese take away was a bit cold when it arrived, while others eat from bins and sleep on the streets in the snow. I am not saying we do not face hardships, or suffering, I do not know anyone who hasn't or doesn't, but I am saying these things we aren't happy about are all temporal and it is the life we are called to for now.
We don't have to like it, but we do have to be thankful for it and accept the will of God.
We have to learn to be content despite many things, because it is all temporal and these light afflictions, as Paul called his severe trials, are nothing to be compared with the glories to come. Contentment doesn't mean we are thrilled about it, but we have come to an amen and accept this is what is best for us at this time, even if it hurts.
I am sure Jesus was not thrilled with being a human being, but He repeatedly called Himself the Son of Man, for the sake of humanity. He said such things as "how long must I suffer you?' He was not always thrilled with living amongst us when we were in doubt and disbelief and sin. But He kept His earthly aligned identity and saw out His purpose.
If you cannot embrace your gender with joy, then rejoice instead that you are suffering for righteousness sake and count it joy, the purpose and calling God has for you that for some reason involves being a she, and a her. Others may not have the same struggle, but may have to find contentment in rejection, abandonment, bullying, unemployment, debt, persecution, disabilities and sickness, in grief and in distress, in poverty and in loneliness, in fear and in failure. Perhaps some of those also are your in life, I don't know.
We don't have to like our lot, but we have to trust God has allowed what is best for us and designed us as we are for a purpose, and that is primarily for his Glory, no matter what we think about it.
We are but clay in the potters hand
So let us not complain
When He spins His wheel and presses in
And at times He causes pain
For when the spinning finally stops
And like all those before us that He came to redeem
No more shall you marred nor broken be,
And your sins will never more be seen.
