Yes I know the whole world isn’t Christian, and I also know that we don’t know exactly when Christ was born.
My point is that the numbering system of our years in our world’s secular calendar is based on the time of the birth of Christ, but that politically correct people are using CE and BCE to disguise this fact. I think it’s a valid point, even though the whole world isn’t Christian. I overstated it a bit to say we are forbidden from saying it. Just saying that they are trying not to use A.D. and B.C., terms which had been in use for centuries.
