metatron,
As you note, there have been a few who would speak up when the situation merited. Most of us were too concerned about our standing, speaking assignments at the next circuit or district assembly, etc. Another emasculating factor is the "respect for those taking the lead" and "double honor" BS, you know the Aaron/Moses thing.
On an occasion many years ago, I politely disagreed with a CO during an elder's meeting. After the meeting, one arrogant kiss ass who had just been appointed city overseer tried to ignite a "disrespect for a circuit overseer" lynch mob, but the furor quickly dissipated.
I thought of several examples of elder courage after reading your post. I will relate just one from the 70's: Gerald Grizzle was serving as a district overseer and met with the elders. He had a prepared outline from the society which he kept to carefully. As we know the 70's presented a lot of dress and grooming issues. The outline recommended that elders take note of how folks were dressed and groomed when attending church services in our respective communities, the idea being that JW's should reflect at least that standard if not being even more conservative. One very young elder raised his hand and was acknowledged. I still remember his words almost verbatum: "Brother Grizzle, with all due respect, since when do we allow Christendom to set the standard for anything we do?" You could see the blood rush to Grizzle's face. He folded up the outline and aborted the meeting, saying something to the effect that he could see that instructions from the faithful and discreet slave were not being given appropriate honor.
