This video talks about the effort of a British high schooler to wear a chastity ring, a small bracelet that declares her intention not to have sex until marriage. Her school has banned her from wearing the ring because it violates their policy against wearing jewelry. Sounds fine right, blanket policy and all.
But the school's policy permits Sikh girls to wear metal bracelets because they are an "integral part of their faith" similar to the head scarves worn by Muslim girls.
It seems like a double standard since the chastity ring is probably an integral part of her faith.
The school girl's father noted that the British government has had a long running campaign to suppress the expression of Christian faiths but at the same time being sensitive to Muslim, Sikh and other non-Christian, non-Jewish faiths.
If the school wants to have a no jewelry policy, fine, but it must be applied evenly regardless of religion or religious overtones. If you allow exceptions for one religion's jewelry, you must allow it for all relgious jewelry.
