Do any gentiles use the BCE thing? You certainly know that it is based on the birth of the baby Jesus, our lord and savior. You seem to have an aversion to using his name. Do you use words like Wednesday, Thursday, January, etc? Do you find them offensive? I’m a follower of what the 21st koan of the Mumonkan calls “Ein aufgetrockneter Schmutzspalel.” I’m really not offended by anything, but it’s really sad to see Western civilization going into the crapper.
I don’t find BC AD offensive, just inaccurate. You are free to believe in your mythology. This is America. We have freedom of religion.
You apparently find other religions to be offensive. Perhaps you could restart the Crusades.
