The trans murder rate is particularly high in places like Brazil, from what I've read. But that's due to a lot of issues: high murder rates generally, attitudes towards homosexuality and prostitution, drug abuse etc.
Most of the transwomen I've encountered are white, middle class and home-owners, though I'm not sure how many went through to HE. One or two have been wealthy professionals. One was in the army. Those are the older ones. The younger ones are very middle class: students and young graduates/ professionals, nicely spoken and literate.
The transmen I've encountered are different. Fewer of them and they tended to be butch lesbians, much more working class and sadly too often from family backgrounds that included abuse.
How marginalised can transgender people be when they are publicly represented by people in positions of influence and power (people like Pip Bunce, Martine Rothblatt, Rachel Levine [US assistant secretary for Health]) Many more, but I have a poor memory for names.
There are transgender people visible in the police, the army, in medicine in this country and abroad. They are much more visible and much more powerful than, say lesbians and gay men, who had to fly under the radar for years. For years unmarried men and women who wanted to stand as political candidates were advised to marry in case people thought they were gay or lesbian. We now have transgender candidates like Sarah Brown, Heather Peto, Lily Madigan et al.
It's a real kick in the guts for us older gay and lesbian people to keep hearing how marginalised and powerless trans people are. Many of us spent the first half of our adult lives as literally second-class people: with fewer actual rights than everyone else. Sorry, don't mean to moan — but perspective does put a bit of a spin on it.
