I believe the Wiki pages change an outmoded reference to historical dates.
I believe that at this time in human history it is appropriate--even overdue--to modify Wiki pages that refer to those years prior to the convention identifying the year "zero" as the birth year of Jesus of Nazareth, commonly referred to as BC [before "Christ"] to the now commonly-used and non-discriminatory reference of BCE [before the Common Era], and that years after the year zero to CE [the Common Era]. [Of course, the year zero does not exist in the "Anno Domini" system--in use since 525 CE to number years in the Gregorian calendar and in its predecessor, the Julian calendar. In this system, the year 1 BC was followed by AD 1.] There is obviously no insult to any religion to make this change--to the contrary it is more respectful of contemporary religious, even agnostic, diversity--and it would recognize that those who do not view Jesus as the Christ [from 'Chystos'--"savior" in ancient Greek] not be implicitly denigrated when referring to historical dates and for not believing he was the Christ. Of course, existing literature employing the "old" conventions should not be changed, even if it could be. Extant literature using the AD and BC conventions is embedded in our common history and history should never be sacrificed to changing moral perspectives. I hope that the Editors of Wikipedia consider this suggestion with the thoughtfulness that is at the core of this leading encyclopedia of humanity's history and knowledge.
