I will have a look at that thread to see what you mean. I think xenophobia may be too strong a word. The problem is that on the Net, you can make a remark which would be quite inoffensive in a pub, perhaps. If somebody says, "Bloody Cornish sheep shaggers!" to me in a pub, I can appreciate the spirit in which it is meant. You have often pointed out that we have to be very careful in how we express ourselves here - and of course you are right. I'll check out that thread later on.
