The "Evil Apostates" held signs up at our convention. I saw one regarding 1975 and it referenced a 1968 WT. Many (possibly 20) years later I looked it up and saw the article regarding "Why I was looking forward to 1975"
The generation change was the ultimate. They NEVER admitted that they made a mistake.
Later blood became an issue as well. I knew that I would NOT let my family die and then the WT change the issue to one of conscience.
