@OP probably
IIRC It was a standard used in the western world for well over six centuries tho, so it'd be a pain in the ass to come up with a new one
That's why the Common Era alternative is a name change, it doesn't actually change the numbers at all. It's impractical and unnecessary to change the point in time.
The change sort of comes because some people feel as though they need to score more victories over a religion that's becoming more and more marginalized as the years go on
The Jews weren't trying to "score a victory", they were avoiding denying their faith. They shouldn't have to say "This happened 100 years Before Christ" because they don't believe Christ (their messiah) has arrived yet. And neither should anyone else. I don't want to say I live in the 2014th "Year of our lord (Jesus Christ)". This is a matter of dignity.
Rant about Christianity being supposedly "marginalized" as it dominates my country:
It sounds like there are parts of the world where Christianity is so powerless that people are fine using its prayers in place of scientific terms. That's not true in America or MANY other parts of the world, though. The Christian Right (which doesn't represent all Christians, but sure as hell tries) works tirelessly to legislate religious "morality" and keep their symbols in government in schools. They do an amazing job, based on these stats (from 2010):
89.3% of Congress was openly Christian, 8.4% Jewish, and 0.6% unaffiliated. There was one atheist, the first ever and last since.
78.4% of America was openly Christian, 1.7% Jewish, and 16.1% unaffiliated.
So no, Christianity does not get to play the victim card here. Judeo-Christianity is massively in the majority AND wildly over-represented. The only reason the USA isn't a theocracy is that most Christians here are decent people who believe in freedom and the principles of the nation. (And only going to church on Easter)
Imagine if these terms asserted the truth of any other active world religion, and thus denied Christianity. Even casual Christians would be uncomfortable with it, and for good reason.
Mainly it's because using religious terms to describe systems of measurement sounds completely bonkers in a world where it's rapidly approaching popular opinion that science and religion are not allowed to exist together
However if standardizing dates means one more step towards globalization, I'm on board.
Religion was always welcome to use the scientific method
And in fact, it did... Very religious people were often major innovators. Sure the Catholic church tried to squash some dangerous ideas, but Catholic monks were librarians, scribes, and teachers. Not many people were educated in that place and time, or dedicated to lives of observation. They preserved the knowledge of Rome and made advances of their own.
There are still plenty of scientists who are religious, too. Not those fundamentalists who crank out untestable theories under the guise of "science", and play the victim whenever they're called out on it...
But there's a big difference between choosing names for terms from mythology, and naming half of all time "Christ's dominion"
