Putting aside content for a moment, and the obvious question about what influences and information this child has been exposed to and by whom, the fact remains that this child is extraordinarily gifted.
I don't think my own 7-year old or any of her friends could write something that demonstrates such depth of thought and expression, however flawed.
This is an extraordinary work from a 7-year old. Kind of like a really socially warped Mozart.
You can take that tongue out of cheek, now...
What on EARTH makes you think this was actually written by the 7-year-old?
