The article did not make me think of trans. I went looking for images to illustrate my thoughts.
I had been think of a youngish trans woman I know, who is partway through physical transitioning, and is hoping to alter her voice. When we talk, I hear a mellow, light tenor voice, and I also hear how much happier and more relaxed this person is now than they were when I first met them 10y ago.
Trying to understand why my acquaintance would want to put herself through it. Trying to reflect upon my own experiences to understand hers.
Most of us modify our bodies or our appearance to some degree. I have pierced ears for practical reasons: clip-on earrings hurt. I wear bras that make my boobs look 20 years younger than the rest of me. I don't have any tattoos, but I have considered getting a cosmetic one.
All these things are so normal that they escape notice. It's only when the changes caused by them become very obvious and inescapable that observers become uncomfortable about them. But presumably the people making these changes to themselves become more comfortable about themselves, whether for artistic reasons, or sexual reasons, or emotional reasons, or any of the other reasons suggested in this thread.
I have drawn no conclusions. I'm still thinking.
