If only I was cleverer. I would then have spotted some wicked irony in 'Caribbean - UNCHRISTIAN!'
The headline of the Sun's article was 'Fury at school's PC Yule song', and it moaned about the lyrics of 'The Twelve Days of Christmas' being changed to reflect a bit of a calypso flavour because, dammit, Christmas is for Christians!
The irony? 'Yule' refers to a Pagan festival. A Yule song wouldn't be Christian at all. The bozos at the Sun are so ignorant of what they say is their own religion, they didn't even know.
And they're happy to associate Christmas with a Pagan festival, but not the traditions of a predominantly Christian region.
