God with a capital 'G' is reserved for the beginning of sentences and for those people who elevate their version of deity to proper noun status. I only concern myself with the former.
Disc-without knowing why you were corrected, I assume you lumped atheists together in some improper fashion. That is a mistake on your part that is going to be called out. Your attempt to flip the script by claiming someone was vague in using 'god' without clarification fell flat because the discussion was with christians, about Christian concepts. (As I fadingly recall.) There was no doubt in my mind...if there was for you, you could have asked. Instead, you made a grand 'Ha-Ha!' spectacle of things.
