I maintain my earlier point, which was that people generally only express group "offense" when they stand to gain something by it, whether it's a political advantage, some monetary benefit or other, or to evoke sympathy (and people love getting sympathy), or to demonize the person they're accusing of offending them.
When none of those motives are present, people generally don't whine about being offended.
Personal attacks are another matter.
As for the sausage-which-looks-like-a-twanger photo, I'll admit that was a bit off. Things which evoke physical disgust and/or make people feel nauseous, well yes you have every right to complain about that.
But as for the original cause of this whole discussion, which was my use of the word "pussy" in a thread title, well I think there's a little hypocrisy going on here. Not to have a go at Beagle, but he was one of the ones who agreed that it was offensive, yet I notice he made liberal use of the word "wanker" in another thread, which is a sexual curse word and certainly not family-safe in some cultures. Not that I was offended by it, despite being one of the most furious wankers in existence
