Shakers pavlov112 and Anitanola sent along this story in the Boston Globe about a set of identical twins, one of whom is a young woman who is trans.
The article is problematic in places (it starts out with a heapload of gender essentialist tropes, for example), but it's definitely worth a read to see what this family has gone through. The obstacles a trans* kid faces even with a supportive family and access to trans*-specific healthcare services are enormous. It's also yet another good (and sad) example of how prejudice is something that children are taught, often by adults who cloak their intolerance in "safety concerns" and religious moralizing.
Anyway! Go read it!
