The answer is obvious? Really? You say that, then you say you think they will be reverted back to the gender they were born as. How is that an "obvious" answer? Sounds like you've still got JW in you. Only a heartless God would force people to be in whatever gender they were assigned at birth, regardless of how they feel and how miserable they are not being allowed to be their true selves. Sure, He could easily make them happily accept the way they were born, but that would be robbing them of their free will, and last time I checked, that goes against His own principles.
