Here's yet another British Cultural Abdication Alert: the cross is banned while Sikhs and Muslims are allowed religious symbols. From [1] AFP, with thanks to Sr. Soph:

LONDON - A British schoolgirl has been barred from wearing a crucifix necklace in class, the Daily Mail reported Saturday.

Samantha Devine, a 13-year-old Roman Catholic, was told by teachers in Gillingham, south-east England, that it breached health and safety rules, the paper added.

Her family reportedly says it will fight the decision and has accused the school of discriminating against Christians because Sikh and Muslim pupils can wear religious symbols.
