To be or not to be PC

It seems like everyone's falling over themselves these days to take offence at some minor infrigement of the PC rules, so when I realised that one of the assessments I was planning to give my Pakistani students had a pet dog in it I wondered what I should do. Would they really, as Muslims, be offended by just a picture of a dog? Certainly the staff who observed my last year's training classes would regard it as 'culturally insensitive' but they tend to be over the top and I'm not sure we should kowtow to nutters.
In the end, I did the only sensible thing and copped out. I didn't change the questions but I haven't used them either. Not till there's some definitive answer, or preferably precedent, that doesn't involve people being given warnings or losing newly acquired jobs.

Entered this competition this week. Don't know anything about it, but sometimes that random element makes it all the more fun.
