The attitude adjustment problem starts at the top. All I ever learned from the Watchtower was how to make excuses. In all my years at bethel, not once in morning worship did I hear the words: "I'm sorry" or "We're sorry". I never saw those words in a single watchtower in all the decades of my life.
I did however regularly hear and read the words "The FDS is not infallible". More often than not, those pathetic words of an excuse are usually not even uttered by the GB themselves, but rather their minions writing the WT for them. Or somebody giving a talk that is not a GB member. I have downloaded almost every recorded talk by all the GB members that some Witness uploaded. Guess how many times they said "I'm sorry" ... ZERO.
I come here though, and see apologetics like Doubtfully and Spade/Alice and Reniaa/Debator - you know how many times they try to quote the GB saying they're sorry? ... ZERO. But every other post seems to rationalize them with the "no infallibilty / not inspired" excuses, over and over.
So you see - I am one of those that have learned from example. I don't know how to adjust my attitude. All I've ever seen are those who tell me to follow their example, never even say sorry for their major errors. They know how to twist words and blame others, by using expressions like "jumping ahead" and "Jesus and Jehovah trust us, so should you". Therefore, I wouldn't know where to begin my attitude adjustment. I'm afraid I'll just have to continue in the same stubborn attitude that I was taught to imitate in the Watchtower.
