I don’t really feel insulted by the Jews not using the term, as you say, most of them (not all however) do not recognize yet that Jesus Christ is the Lord. Someday, you will though :)
It is still strange for the Jewish scholars to not recognize the terms however, the date range is the same...it is rather rude...don’t you think?
I wonder how you would feel if the insult were reversed...
It’s not “rude.” It is, however, extremely rude for you to demand that any Jew, especially a Jewish scholar, define any year as being “Before Christ,” when no “Christ” has come. It’s no insult, unless you are insulted by us uppity Jews not toeing the line and converting. In which case, you can, once again, copulate with yourself. We ain’t going anywhere.
