Hello SBF,
I don't see anything that I personally would be very offended at, but I do notice a general tendancy to use charged Watchtower-esque words and phrases in your writing, which can be tiresome in quantity. (Please don't take offense at this - I'm merely trying to give you my frank opinions.)
For example, at the beginning of this post, you observe that
Sometimes he sides with apostates and sometimes he sides with the Witnesses on controversial issues
which I find to be a rather absurd characterization. I think it would be more accurate to say that sometimes he agrees with the Witness version of history and sometimes he does not. Why introduce the Watchtower-loaded word "apostate" into the discussion?
In your actual correspondence, you say
I find it curious that you ridicule the suggestion that this reference indicates blood transfusion was 'banned' already in 1944
I used to write just like this, because it is a very Watchtowery way of writing. They love to say that people "ridicule" or "deride" or "decry" certain things, when in reality the person may simply disagree. I only bring this up because people often take offense when they feel that their position is being caricatured.
I think he might well have taken offense to this statement:
I would not like to believe that you persistently inhabit such a cynical attitude with respect to the history of Jehovah's Witnesses, while all on your lonesome.
Honestly, I don't understand the purpose of this sentence. My mind struggles to understand what you might mean, and the only plausible interpretation I come up with is that you are being protective of the Society and can't bear that others might not be as generous as you in their opinions of their motives, and that you are attempting to invoke shame over such a cynical attitude by suggesting that he is the only one that has it.
That's about it. All in all, I think it's a fairly tame letter. My comments were made without knowing the context, either, so apologies if I've gotten the whole thing wrong. Those are just my thoughts.
It is interesting to see you having this type of discussion. Hope my comments did not offend.
