There are plenty of vulnerable groups - disabled people, people with learning disabilities, some old people
My risk assessment for my son is that he is more vulnerable on the basis of his skin color, than on his liking for lipstick. And that many areas where his risk could manifest, employment being one, would actively cater for his feminine presentation while ignoring issues of ongoing racial bias within their organisations.
At his school, boys like him who transition, or who are thinking about transitioning, have quite high status among peers. His educational risk is more about his dysgraphia, frankly.
The college he is seeking to attend is explicitly trans-friendly. Again, his risks there are more around a genetic susceptibility to addiction, and exposure to a high income area where drugs are very available.
People need to be far more responsible and nuanced in the way they discuss risk. Many of the loudest trans voices in the UK, for example, use statistics inflated by the inclusion of sex workers. We all know that sex work is a very dangerous job; remove sex work from the equation, and risk dimishes greatly.
A white, middle class male transitioner working in IT is actually at less risk, for example, than many so called 'c*s' persons, including those in poverty, women and girls, people with disabilities, and gay and lesbian people.
I'm really very tired of trying to have a nuanced discussion on these issues, in this case to directly help the OP, and getting slammed by what I can only describe as simplistic sloganeering.
