You are right. For some reason, they're threatened by the book. But, I say that this is a free country, not Communist China, where this child would be persecuted for saying these things.
While I wholesale agree with you . . .
to nit pick a bit . . .
this country is marginally free on the surface.
Al Cuppett asserts (as have many others) that the PTB have 100,000 guillotines warehoused in the USA ready for exterminations . . . along with many other more mass oriented means. He has a pic of a rail car full of them.
He’s the former staff officer of the Joint Chiefs of Staff.
As the kid's father (a minister) said (to paraphase), 'little kids don't describe heaven from a theological point of view...they just say what they saw.'
This story seems perfectly plausible particularly because the father takes pains to present it in an intellectually honest way and to make sure that he doesn't, in any way, lead the kid or put ideas in his head.
This simple (and simply told) story is self-evidently true and will be a great comfort to many.
As an added note, God's obvious intention here is not to use this story to win souls but to comfort those who love Him.
