I'm holding the line at English.
BC is what is used here in AMERICA, where FR is based (1 hr north of me) and where I’ve lived for the last fifty something years. Then comes along an emboldened wave of stinking commie rats, and now here in the USA you hear rat educated people SUDDENLY pushing BCE, when you didn’t hear it being used before. Go join em if you like. Call homosexuals “gay,” call men who mangle their bodies “women,” call abortion “choice,” call NAMBLA “love,” call good “evil” and evil “good”... and enjoy your party. But if you expect to converse with me then you’ll not pretend that 2011 represents something of your own (man’s) making without being called out.
And the last reference you want to use here on FR is Wiki unless it’s about a simple self evident subject. I couldn’t care less what’s in Wikipedia. I’ve lived here and I know from factual experience that Americans have traditionally used BC to express years Before Christ, and AD to express “Anno Domini,” which is Latin for “year of our Lord,” representing the number of years since... well, you guessed it.... the birth of our Lord and Savior, Jesus Christ.
