@ OP - I sincerely appreciate the information you have shared with us all but I have to respectfully disagree with you.
If you listen to talks and commentary from the GB one can see that they are deliberate in their use of specific phrases that are used to elicit a specific physiological and psychological response. Simply speaking, they are using mind conditioning techniques on the members. Now the question begs, do they write their own speeches or is there someone else behind the curtain we cannot see?
