Like a moot point I assume. "arguable: open to argument or debate; "that is a moot question" " Why argue if cows have eight legs it is a mooo-t point anyway.
First, where the word 'moot' is, it was 'rude'. This didn't just apply to Atheists just the general idea of people talking about their religious beliefs at inapropriate times.
Then, A mod changed 'rude' to 'cute'. I don't they changed it because they thought it was offensive. I think they changed it just because well...they might have been atheists or they were just trying to be funny.
Now, it was changed from 'cute' to 'moot'. I don't know if it was the same moderator or another one. Just because it generalizes the topic and makes it fair for everyone.
The original title wasn't intended to be offensive towards Atheists. I am sorry if anyone took it that way. All-in-all I don't think they changed it because they thought it was offensive. I think they changed it just to change it...You know?
