I remember a professor saying we should use BCE and CE because BC and AD would offend Muslims. From her surname I believe she was Jewish.
Mohammedans don’t mind the use of the terms Before Christ and AD - they use their own Hegira calendar, but BC and AD don’t offend them as “Isa” is a prophet in their philosophy
Her ancestors don’t matter. She was a professor and thus 99% chance she was an indoctrinated leftist.
