That's well below "racist" on my list of insults, but is less funny and includes more potty language than the dig at Americans that provoked it. I always assumed septics were fair game in the same way as France is fair game for CNBC reporters.
Here it is for you Ed. it wasn't supposed to be funny. I was being entirely serious (though possibly insulting to Neanderthals). So you can stop trying to see the humour in it. The comment that provoked it may have been a dig at Americans (or whatever smartarse word you're choosing to use this week to describe them) but included a dig at another nation. A fairly base one at that. But y'know, I'm not at all surprised that you'd choose not to see it. Do you need smileys in future?
