Don't do PC, I consider it more PS (Political Stupidity!).
Latest stupid idea (being taught to my daughter at school - which is what prompted her to write Patriot) is you can't use the word 'black' at all - you don't have a 'black man' any more' you've got to call him a 'rainbow man', and you don't write on a 'black board' it's a 'rainbow board'. There's one coloured guy in their class, so Melissa shouted across the class "hey, what colour are you?" - "I'm black!" - "no you're not, you're rainbow" - "am I f**k rainbow", so that went well
