"We UNDERSTAND..." is established "Watchtower speech," among "those mature," of course. If you speak to long-time elders, go the KMS, etc. you will reguarly hear about some earlier doctrine that was then later replaced/reinterpreted as "Well, the understanding in those days was..." or "that was the understanding back before blah, blah, blah."
It's like the constant use of the passive voice in WTSpeech: "it has been decided that..."; "the decison was made to..."; or the corporate mentality: "the body of elders has seen fit to..."; "the Governing Body has decided..."
It's all part of the entrenched procedure to abandon any personal responsibility by individuals. It's got a long history in the WTS. Nothing new here, really (and isn't that shocking?!).
Now this "We LOVE this teaching" thing IS new. It shows how deeply averse they are to the idea of doing any kind of objective, empirical, educated research as a basis for doctrine. Not that they were ever really into that, except perhaps a little bit by Fred Franz, but with all his eccentricites constantly getting in the way. However, the current GB has latched onto the "we LOVE this doctrine" thing like GB I never had. In a certain sense, GB II is a bit more transparent, openly displaying their ignorance far more than GB I did. They seem proud of it, in fact.
