I did that for years and never really felt "out" until I quit going entirely. But, it's a step in the right direction. The less contact with the poo poo, the less it's in your head.
But I remember at the end sitting there and mentally arguing against nearly everything the speaker or the Watchtower was saying. The whole meeting became a mental debate for me, with me sitting there wishing I could jump up and say out loud everything I was saying in my head.
It did help me realize that the elders are not geniuses nor are they even very good scholars, not most of them...not at all. It was no great tribute to me that I could constantly find holes in their reasoning or "facts" once I removed the taboo from my mind that we must never go against the Society, i.e. anything in the Watchtower or what was said by the elders.
Gee, just saying that "Never go against the Society" which is an actual catchphrase our presiding overseer used over and over again, sounds like something directly out of an Orwellian dystopia, doesn't it?
