We are told however, that “trans” is something you are, not something you believe.
The demands they are making are based on that assumption: that this is something real that they “can’t help”.
For some, it may be true that this is something over which they have little power. Those with mental illnesses have rights as well and those should be extended to those transitioning and in distress.
But I return again to the fundamental problem that there is not a discrete group of “trans people” at the moment. The definition pushed by those demanding rights is not your definition. Laws were created based on your definition, but then changes to the definition were pushed and that was a deliberate act.
So define “trans people” however you wish, but I think the term is no longer fit for purpose, if ever it was. There are people suffering from gender dysphoria, some of whom are pursuing physical transition as a treatment, and yes those people need to have rights.
But I see “trans people” and “gender identity” as being made up concepts which were invented to describe inner feelings of some kind. Yes, some people believe in them, but they are not asking us to allow them to believe in peace. They are demanding access to groups and rights where they do not belong and demanding that others adhere to their beliefs. Moreover, as we see in the courts, the adherents to “gender indentity beliefs” are hounding others that do not believe in ways that are illegal.
Which is why most of the women here come to believe there is no middle ground: only appeasement.
Pasting this follow up comment from @PriOn1 as I really think it's at the heart of the matter. Trans people have the right to believe in this or any other unfalsifiable belief such as reincarnation. I have the right both to disbelieve and express my disbelief in their belief system, which I consider regressive, harmful and based on sexism. Whether others consider it "useful" or not.
