I agree with this. There are a lot of role models for LGB kids. There are openly gay legislators, entertainers, scientists, authors, actors, etc.
There is a HUGE need for transgender role models. The world is full of accomplished, intelligent, hardworking trans people who make great contributions. But the average closeted trans kid who is terrified to come out be cause he/she is a freak doesn't hear about them.
I'm actually working on a way to include Lynn Conway in the history of computer science unit I teach.
