The last Public that I gave, I didn't use the name Jehovah for the first 25 minutes, using instead God or Lord to refer to the Deity. Then I noticed that my failure to use the familiar word made the audience very restless. Strangely everyone was wide awake, as if they realized something was wrong. When I started to sense hostility, I began referring to God as Jehovah. Then, once the magic word was used the audience settled back into their usual routine. Those who liked to sleep returned to their slumber, those whose minds liked to wander dropped their frowns and went back to the blank stare. While those who liked appear "theocratic" went back to writing notes, or whatever.
Since leaving the JWs I don't use the term Jehovah, unless referring to the Witnesses. Being a person who respects other religions and people of other faiths, even if I disagree with them, I don't use the word Jehovah in a disrespectful manner. However, I did have an interesting experience regarding the name for God. For a few years I was engaged to a Jewish woman and attended Synagogue with her and took Jewish living classes. I noticed that using the term Jehovah didn't offend her. However, she didn't like me to refer to God as Yahweh as she felt this was disrespectful. Jehovah is a made up word and had no meaning at all for her. But Yahweh did and shouldn't be pronounced.
