After some thinking, here is my response to your suggestion.

It's true that the term is loaded, I very much can confirm your observation/experiences.

But I still wouldn't invent a new one. That's the interesting thing about the fact that the term "God" stands alone, is basically undefinable and doesn't want to offer any connection to other definitions. I think that's exactly how it can allowed to be.

Avoiding loaded terms because they are loaded would justify, for example, that nobody says "Hitler" anymore and soon it would amount to a swastika only being associated with a load, which is illogical, don't you think?
What can the swastika do for being viewed one-sidedly?

The in advance given politeness of not wanting to put off another person who is in dialogue with you by not using a loaded term, for example, raises the question of where this shyness comes from. It implies that the interlocutor shuts down from the outset, yes, I agree. How could he realize his reluctance other than by a term which he himself loaded negatively, though? Is there another way to create a space for openness?

Can you decide not to bother with it and demonstrate impartiality precisely by using the term in spite of its loaded meaning? To un-load it again? My answer would be "yes", that is actually what represents a scientifically operating person.

To deal with bias, for me, means to be aware of my own and not having it excluded for reasons of my comfort; this may lead to establish my bias. I need being somewhat uncomfortable and "disturbed" in order to engage. Otherwise, I may find myself in an echo chamber.

However, a loaded term would not be guaranteed to be cancelled out by using an alternative term.
If one is determined to be exclusively negative about it, he is going to do so with either term in the same context.
Basically, you can always take offence at a term, regardless of whether it is an ancient or modern one.

Though, what I could do - and I attempted that down below my post indirectly - to give official biblical information to the figure of God. I could have done better, maybe.
