I got to someone over that, when I said CE stands for Christian Era.
I had to take a Religion class in college as a requirement. The professor was a lapsed Methodist. He kept marking down my papers for using BC and AD, and told me to use BCE and CE. I was a bit older than most of the kids in class, and I didn't toe the line with BS like that, and simply asked him what the CE was in BCE and CE, and stated that it was a distinction without a difference. He backed off.
