So basically, you claim that one exception to the general rule is enough to form a rule that "divine heritage doesn't mean jack"?
There was not a single retarded child of Bhaal in any of the Baldur's Gate games. Enough proof that divine heritage prevents retardation.
And how many of Bhaal's children have we seen, really? Ten, tops? Out of hundreds he spawned? Not really a representative group, to be honest, especially if you take into account the fact that you actually have to fight most of them, and fighting a drooling idiot isn't anyone's idea of heroic fantasy (i hope ;D).
Also, don't forget that some (or perhaps, most) of the children of Bhaal were, in one way or another, mentally ill. They were megalomaniacal, psychopathic, paranoid, and inclined towards the ways of Chaos. That and some "special magic powers" is what Bhaal gave his children, not permanent "protection from idiocy".
