PC is predicated upon a principle of designed ignorance. In the case of CE the question of the origins of the common era are left unspoken. It remains, however, for anyone careful enough to skin the surface, anno domini nostri Jesu Christi “the year of our Lord Jesus Christ.”
What’s common about the Common Era? Still can’t figure that out. When I read CE, my internal voice says “Christian Era.”
When I first saw “CE,” I wondered why the change from “After Christ” to “Christian Era.” I still read it and say it “Christian Era.”
