So yeah, my avatar is a picture of me before HRT (I use it because all my other pictures are public and can be reverse image-searched, and for the sake of my vanity since I'm an older lady now!). I was often mistaken for a lesbian in queer contexts even when I had a short, male hairstyle. So I pass pretty readily, and have lived my life as a woman considered to be of above-average attractiveness.
I've had a lot of experiences with cis people that have pissed me off related to this. I actually have a cousin who's trans, but is more marginalized by my own family because she's not considered to be "beautiful." When I stayed with my best friend in California her roommate expressed discomfort about having a transwoman stay at their apartment, but said after she met me that I was fine because she expected me to look like a man and I didn't. An ex-boyfriend told me the story of how he was once "fooled" by a transsexual, and when I objected to his use of the word "fooled" and how I wouldn't like it if he talked about me that way (he knew I was trans before we met), he said, "I wouldn't say that about you because to me you're just a woman."
And in all those cases I've tried to communicate that it's a big problem that non-passing transwomen are being categorized as "not women" when we're all "another type of woman," whether we pass or not. It's like being a Muslim woman or a woman from Germany or what have you. Being a transwoman is being a particular type of woman, and we all share that experience whether other people can tell or not. That's what I try to communicate. And I respect certain people's right to say they don't want to belong to the trans fold, just as many women who are born within a particular community end up choosing not to identify with that community as an adult, but I personally would be uncomfortable just disappearing among the crowd of cis women and not identifying myself as trans.
But I also know that I have a lot of work to do in terms of getting over my own transphobia and socializing widely in my own community. I derive self-esteem from being attractive, and I know that triggers feelings of insecurity in other people but it's hard for me as an insecure human being (like many others) to control this behavior. Plus I've also experienced the phenomenon of people befriending me because they think it makes them look good to be associated with a passable transwoman, which has been another source of annoyance. But part of my reason for joining this forum is to hopefully work through those issues.
And finally, yes, attractive people get advantages in this world, but can also be shunned because they trigger other people's insecurities. But it doesn't mean we need to settle for that and we can't ourselves fight our own prejudices, especially when we all belong to the same community.
