Yeah, I'm being rhetorical.
Just because there was a space on the sheet - because it was a useful thing to include for some classes - in absolutely no way implies that everyone should have one or the game demands it in any way.
The AD&D character sheets had a space for 'Helmet'. Does that imply that every class is presumed to have one?
(Rhetorical answer: Nope.)
At the risk of getting political, if this was about anything other than 'Diety' there would be no problem. But, having grown up in an extremely religious place, I've seen this line of argument before - and it's the old 'D&D is Satanic' thing in another guise.
When someone is sensitive, confused, or vulnerable about their own faith, this game can be incredibly triggering. I've seen it myself, in a friend who was a fundamentalist Christian who was young and conflicted for various reasons.
I came across a bit crass before, but really feel bad for the OP, because the idea that this game would be oppressive means there's a lot more going on there that should be answered somewhere outside the game. I don't think this thread will really answer what he/she needs. I do wish them well, but this whole thing isn't really productive.
