Some of the posts in this thread so far actually demonstrate the very thing that I'm getting at. In my experience, when I ask a Jehovah's Witness to imagine a scenario where anything about reality is different from their religious expectations, they won't. Either they dismiss the question altogether or try explain why it's irrelevant.
As you identify as Christian, how would you answer the OP? Do you imagine scenarios that are different to your own beliefs and answer them? If you are a Christian, why would you even do that?
Here's a possible example:
Me: What would you do if one of the Hindu gods revealed that Hinduism is the true religion to you, personally?
JW: It's not true though.
Me: No, I mean what if they did? What would you do?
JW: That couldn't happen because of X, Y and Z.
Me: This is a hypothetical scenario, asking if it could happen.
JW: This question is meaningless and has no bearing on reality.
If it is impossible for us to even imagine, then why would we answer it? It really does have no bearing on reality for us...I live in the real world, not Fantasyland. I have real problems to deal with, so why even concern myself with something that makes no sense? Its a dumb question.
You say that you aren't taught to avoid hypothetical questions, so why do you do this? I find it very easy to consider the consequences of my fundamental beliefs being different. Surely you can do it too. I'm not saying that all of you are like that, but all of the ones that I, personally, have spoken to about this have been.
If you find it easy to imagine that your fundamental beliefs can be wrong, then you obviously have no Christian conviction. Indecision is not a good foundation for faith.
James 1:5-8:
"So if any one of you is lacking in wisdom, let him keep asking God, for he gives generously to all and without reproaching, and it will be given him. 6 But let him keep asking in faith, not doubting at all, for the one who doubts is like a wave of the sea driven by the wind and blown about. 7 In fact, that man should not expect to receive anything from Jehovah; 8 he is an indecisive man, unsteady in all his ways."
My conviction makes your hypotheticals seem ridiculous. So seriously, why would I even give them headroom?
