Short Answer To A Whine

I used to always use CE (common era) and BCE (before the common era) to annoy fundamentalists. 

Now I use those when I want to annoy fundamentalists and BC and AD when I want to annoy atheists and their allies. 

That's how you can tell who I want to annoy when I use those. 

For more information, I try to remember to use First and Second Testament because there's no place I can see that the first one was withdrawn.  But it's my experience that the clueless are even more clueless when that's done.
