In the context of this thread, that looks like a non-sequitur. It doesn't seem to have much to do with the provocative assertions that you've made in your earlier posts.
Like I said, I think you have
implicit faith in your reasoning about theistic matters.
I have been around for a while, and the one thing that theists surely have managed to do is to wipe that smile off my face.
You might end up bitter and confused like myself as well!
1. "Does God exist?" etc. are useless questions"
Why do you believe that it's "useless" to ask whether God exists or to ask another individual whether he/she believes in God?
I gave examples of situations where the question may come up, the people being:
Christian proselytizer in the street; poster on an internet forum; philosophy teacher in class; friends and family; one's boss; one's enemy; the seeker.
Of course, this list is mostly just about types/groups of people (so with "Christian proselytizer in the street", there is also the "JW in the street", "Mormons at your door" etc.; akin to one's boss is any similar situation with someone who is higher up in the hierarchy than ourselves; etc.).
What conversation, for example, can be had with a Christian proselytizer who stops you in the street? My experience is that there can be none. They insist in their way of approaching a topic, they might ask questions like "Do you believe in God?", but there is no room to actually discuss what the terms mean to each party. (I thought this was obvious.)
Further -
2. "Now consider:
Who is in the position to meaningfully ask them of another person?"
What sort of "position" do you believe that somebody must occupy in order to "meaningfully" consider the question of God's existence or to ask others what they think about it?
Do you think that, for example, when a Christian proselytizer who stops you in the street to tell you about Jesus and the Gospel, really cares about whether you believe in God and what the words in the question mean to you? Do you think that your reasoning about theistic matters will significantly improve if you talk to such a proselytizer?
Or is he there to shove his message down your throat and say you will burn in hell for all eternity if you don't do as he says?
3. Except that when it comes to discussing God, given the way "God" is usually defined (as omnimax), then the one who doesn't have proper knowledge of God is left to the mercy of those who (claim to) do.
"Left to the mercy" in what way? That needs to be explained.
4. Basically, theistic discussion is an infinitely unfair one.
The theist potentially has infinite power over the non-theist. How this plays out in actual communication is just one aspect of it.
I'm clearly not understanding the point you're trying to make there. (But I do have to tell you that your assertion sounds a little grandiose.) What kind of "infinite power" do you claim theists have over lesser people (like me)? Power to accomplish what precisely?
If you agree that you do not have sufficient knowledge of God, then you are, simply logically, vulnerable to anyone who might have such knowledge.
If you agree that you do not have sufficient knowledge of God, then you have to accept that things that might seem strange to you might be true about God.
But since if you agree that you do not have sufficient knowledge of God, then you don't know what that knowledge is and who has it, or not.
In this sense, you are left at the mercy of those who do have such knowledge, and they can use your ignorance/lack of knowledge against you, and you cannot prevent it.
But what does my lack of fear of eternal damnation have to do with the seemingly unrelated series of assertions that you've been making in this thread?
Everything, this fear is what drives one's inquiry, or at least puts an end to it at some point.
Presumably you have some line of thinking going in your head, something that ties everything together, but so far your posts have been too disjointed and cryptic to clearly communicate what it is, at least to me. Maybe others are having better luck.
I am sorry. I wish I could have a definitive stance.
