CE/BCE

So my daughter comes home and tells me they have changed their social studies and history books not use BC/AD. Instead use BCE and CE. What's up with this? Why are they changing terms that dates have been using for, like, ever.

I imagine it is as to not offend anyone non-Christian. But it is still based on the birth of christ, so how does it matter. Bah. Politcal correctness strikes again.

Here is what the wikipedia says...
