I guess what I thought worthy of discussion is whether the community at large considers posts such as the example that prompted the top node to fall within those guidelines

That's a bit of a different question -- "does this post cross the line/zone?" versus "where do we draw the line?".

I understand how people of faith would be offended by the post in question and I think using an expression like that displays poor judgment. However, the definition of "egregious" includes reference to words like "blatant" and "flagrant" and I'm not sure it quite reaches that standard.

For me, I tend to be fairly reluctant to censor unintentional offensiveness. What crosses the line for me in a community setting is more akin to "willful" offensiveness -- comments made that are intended to inflame or incite or hurt the feelings of others. (I.e. "flames" and "trolls".) I don't think the author of the post in question set out to offend and thus I, personally, would not consider the node.
