I know she will have lots of nonacceptance, but not all of it will be about her gender identity. Prolly about her hair, her cloths, sports, or who she is associated with.
When most of us grew up, it was completely unaccepted to come out when we were young, or to even explore that we may be a boy or a girl. For my wife and I, if we had told our parents when we were young, we would be dead, accused of being spawn of satan, or some such. But now adays the acceptance level is going up.
She was able to tell her family and have it supported by them, I have even heard of alot of acceptance in public. Yes, she still has a storm to deal with, but not to the degree that we did. Maybe 85 to 90% compared to the 100% alot of us had to deal with.
