being transgendered as a set of identities that we can pin point and define based on the psychological make up of an individual...I don't see transracial as having a similar grounding in science so I'm not going to do a disservice to transgender people by saying the two things are similar.

"All the world's a stage,
And all the men and women merely players:
They have their exits and their entrances;
And one man in his time plays many parts..." -The Bard
