Fair enough, but I think that this particular group of 10-year-olds would (small g) get enough for it to be useful - your original post left me with the impression it would be so far over their heads as to be useless. If instead you meant that they would get (small g) the WRONG thing from it, well, it would certainly be ironic if they believed Dawkins just because their hearing it made them infer that they should believe it because someone said they should, when what Dawkins was telling them specifically NOT to believe things supported only by the voice of authority.
