Why would a Jewish newspaper refer to a time "before Christ?"
Why would a "Jewish" newspaper not use the Jewish calender and then the date wouldn't be before anything? Because they intend for more than just Jews to read this.
Why would a "Jewish" newspaper refuse to use A.D. and B.C. yet date the article at the top of the page Tuesday? (note: Tuesday and the Christian date is printed alongside the Jewish date for Jewish readers.) Tuesday, named after the Tiw, a god of law and war. Seems to me that if you were sensitive about dating things according to other religions you would surely not use the name of a pagan god for the name of the day. Oh, I forgot pagan good, Christian bad.
I wouldn't take it as an anti-Christian slam.
If you are going to use a dating system that is based on Christian dates yet change the name of that dating system because you want nothing to do with anything associated with Christ, then yes it is anti-Christian political correctness.
