Australian Christians are not very happy, to say the least, about changes to the national curriculum that will see the terms BC (Before Christ) and AD (Anno Domini) dropped from text books in favour of the neutral, more politically correct, non-religious terms BCE (Before Common Era), BP (Before Present) and CE (Common Era).
First devised in the 6th century, BCE and CE gained popularity in the late 20th century to allegedly show sensitivity to non-Christians. The term BP (before present or before physics) is a little-known time scale traditionally used by scientists to refer to the era before 1950, when carbon dating technology became more reliable.
