How do we decide who was really born in the wrong body?

Rachel Dolezal believed she was born the wrong race and was publicly humiliated when it was revealed that she is a white woman living as an African American. Chloe Jennings-White is considered nutty because believes she should be living with a disability and wants to have surgery to sever her spinal cord. Yet, as @Josie pointed out in a recent question, Bruce Jenner was born the wrong gender, became Caitlyn and everyone applauded her bravery.

So who decides that one is ok and the others aren’t?
