So long as I'm not trying to force my beliefs on someone else I'm not sure how this can be viewed as arrogant.
Your certainty, in your belief, that your God is irrefutably real, is entiely in your own head--it's all about you. Rather arrogant to demand that that which you imagine to be real is real, because you believe it real. There is really no better example of arrogance than the ". . . because
I say it is so" that is ultimately the only validation faith requires.
And I certainly don't make demands . . .
Except, of course, for the existence of your God.
You keep coming back to this "demand" word and your definition of what is a demand. Let's look at that.
–verb (used with object)
1. to ask for with proper authority; claim as a right: He demanded payment of the debt.
2. to ask for peremptorily or urgently: He demanded sanctuary. She demanded that we let her in.
3. to call for or require as just, proper, or necessary: This task demands patience. Justice demands objectivity.
4. Law.
a. to lay formal legal claim to.
b. to summon, as to court.
To be clear, I'm not asking for or calling for anything. You seem to be saying that if one person believes something it also means that they are asking or calling for others to believe it as well, as in your comment 'Rather arrogant to demand that that which you imagine to be real is real, because you believe it real", something I have never said, or even thought.
I simply set out what I believe, and others can either agree or disagree as they see fit. If you view this as a demand, then clearly your determination to validate your own argument is getting in the way of a reasonable discussion.
