While he does have a point, Christians are usually not accomodated like those of other faiths, if an organization has a rule against all jewelry, they can’t make exceptions for religious jewelry...or why not pentagrams or upside down crosses for Satanists?
The real question is why a rule against jewelry in the first place? Civilized people have worn it, in moderation, for thousands of years. Perhaps piercings and other bizarre modern “jewelry” is what was targeted, and a general ban was the only practical way to get at that fairly.
Still, considering all the un-Christian functional-atheist types who wear little crosses as jewelry, I can’t get all excited and shout “Persecution!” when all jewelry is excluded—even if certain clothing endemic to other religions is allowed.
I doubt any of the first generation of Christians, and the apostles themselves wore crosses around their necks....they bore the cross of faith in more substantial, and effective, ways.
So, certain religions should get preferential treatment because the symbol of another religion is abused? Sorry, not buying it.
