I don't think there's any right answer to this predicament at this stage, time will tell. If this child does grow up and continues to wish to be a female, then I agree that it is wrong to harshly judge the parents and the child for this situation, but you have to admit that it seems fairly preposterous that a six year old has decided he wants to be raised as a girl. It's unusually early to reach such a conclusion, and an extremely well informed decision made by a very young mind.
