No, it is because this person expects/demands us to believe that he is a disabled woman and treat him as such.

This is nonsense.
A) How do you know what this person expects of others? Do you have a source for this information?
B) It is literally impossible to force someone else to believe something. So even if true, it doesn't matter what they want you to believe.
It's part of what trans activists want. They demand that everyone use the gender that they identify as, so even if a male with big beard and has all his genitalia intact decides he indentifies as a woman we are to believe it's true and behave as if its true by using she & her to refer to him. To refuse is considered "transphobic" and you will be canceled, unless you are JK Rowling or Dave Chapelle. Also a lot of males who identify as women demand to play in womens sports and you are not allowed to oppose it. This sort of stuff has been big news for a few years now but clearly you haven't been paying attention
