The orders and by extension the GB and their helpers are losing the power they once had.
So what if you express doubts. What are they going to do? If they try to accuse you of causing division then you can challenge them on it, make it clear you doubt the GB are correct but they openly admitted to not being inspired or infallible.
You just need to say “I am in no way causing division I’m just agreeing with what the GB said, and yes I think they are correct they are not inspired or infallible, I think they made a mistake with their vaccine mandates and I think they may be wrong about 1914 and other things. But I am not causing division”
and what would be the consequences if you did stand upto the elders and not let them push you around anymore? They could try to have you disfellowshipped but you just have to say that would make you suicidal.
