Hi Firelight,
I think you are expressing what many people think but few actually express. I know when I first came to this site I was taken aback by the different types of people, the different "looks" I'd see. For the first few months as I browsed and read and posted, I got to know many of these people. My first impressions were sometimes based off of appearance, much like it had been most of my life (I know, not fair, just being honest). What I found after a while was sometimes you would have the most passable person with the most beautiful voice and the seemingly ideal life who just had the absolute worst attitude in the world. Caustic, pompous, etc. Just generally someone that had a real mean personality and spirit, but they looked and sounded GREAT!
Then I'd see the opposite too. Someone who might have appeared the opposite, where I'd not be sure of gender intentions or identity, would just not look what I'd imagined a transitioned/ing person to look like. They would have hearts of gold. They would have informative posts. They would be the people who would be there for others. They would be quick to offer their phone number to someone who was in need, sacrificing their own needs for the needs of others.
What I learned over time was that transgender people are just that...people. They come in all shapes and sizes, all different passabilities, personalities, etc. The way someone looks in our world, on this site and other trans sites is just a microcosm of the real world. How many times have you know a really hot person, like super, super hot, to have a really poor attitude. Then you'd have someone that you would just be like "whoa" about and guess what? Wow, they are the most gentle, caring, kind soul in the world. It's a lesson I think we need to remember in trans spaces. You really, truly learn to get past initial perceptions and get to know people for who they are.
The other main thing to remember is that many people are transitioning. How they look now is not how they always looked. I'm posting a link to this video I did on Youtube that shows just my face over 3 years through transition. If you watch it, tell me honestly if through those pictures there wouldn't have been a point where you would have been like "um, scary." But, I'm the same caring, gentle soul I was before. LOL, I sound like yoda, huh? But you know what I mean. If I looked like I did before transition or like I do now or somewhere in between or whatever, I would hope that once you got to know me, your thoughts about me would be the same. That's what I strive for and I continually remind myself of that online and in real life. Good luck on your journey
