I always believed that Jehovah wouldn't destroy all the children at Armageddon. It wasn't fair because they didn't have a chance to learn about him and make a choice like their parents did. (This is before I knew that most adults in the world haven't heard of JW's either!) I figured Armageddon survivors would adopt all the children and teach them Jehovah's ways.
I also believed that if oral sex and masturbation were so horrible that Jehovah was going to destroy people for doing them, then he would have specifically condemned them in the Bible like he did everything else. (Not that I ever do those things of course! ) I was just thinking about the poor, dirty sinners who did!
