I'm not sure what unique perspective you mean, trisher, and don't understand the point you are making.
MW's uniqueness is possibly true because of her trans status, as a holder of a role that was ring-fenced for female applicants only, but there is nobody who can bring a perspective that covers the experiences of all clients in something like a rape crisis centre.
MW's Asian heritage means that she might understand the culture of her country of origin but only from the perspective of someone from her background, social class, age, education and so on. Asia is a large continent with many different countries and cultures within it, and in any case none of us can claim to have a full understanding of anything but our own experience - anything else is learned from others.
Rape victims come from all over the world, and from various subcultural groups within its different areas, so someone from any one part of it can't possibly have the perspective that you consider valuable. As with all such organisations, post holders will have had diversity training appropriate to the role, will ask questions of clients and colleagues and learn as they go along. There really is no alternative.
You could just as easily say that I have a unique perspective, based on my own background education and experiences, or that you, or anyone else has the same.
