Because there is one standard for new students and a completely different one for longer studied students and baptized witnesses.
True. Yet even as a "student" I soon learned that questioning could quickly be redefined as "opposing".
On topic - When my SIL first joined, over 25 years ago, there was still this sense of urgency, even excitement. (1975 plus however long it took to create Eve, maybe?)
Now she and my jw ladies sound repetitive and, I think, defensive. They cannot explain the latest "generation" reaoning, but simply quote it from the magazine, There is still mention of "soon" and "final days" but it really lacks conviction. After assemblies there is a short burst of excitement and I get a few visits but it quickly fades.
That's the main difference I see from the outside.
