That is a wonderfully written and well reasoned letter ! if only JW's will read it and take its message on board !
Just one gripe from a super pedant, you might want to change the spelling of "discrete" to "Discreet", personally I don't care that much, but JW's will find one mistake and reject the rest.
I am sure the G.B think of themselves as "discrete" but the scripture has the similar word with a different meaning i.e "discreet", which of course, they are also not.
