Hey everyone,
To respond further to the questions around jokes - as Justine said earlier, things do become a bit more complicated in this area, because in order not to delete every reference to a country that made mention of national characteristics/accents, we need to be able to use our judgment. There's a difference between someone, say, aping a French accent, because of France's position in the world, and someone aping the accent or characteristics of a country that's historically been oppressed or exploited.
Specifically in terms of Ireland, we can see a distinction between jokes of the "Englishman, Irishman, Scotsman" variety, which are built around a denigration of Ireland, and the 'top of the morning to you!' thread title from earlier this month, which was referencing a colloquialism in a value-neutral way (as was clear from the fact that the OP was heading to Dublin and excited about what she might get up to there). An equivalent example might be if someone were to start a thread entitled "Why aye, man! Gannin doon the Toon; what should ah dee when ah'm there?". I realise the north-east is a region rather than a city, and therefore not protected under the Equality Act, but it's certainly experienced its share of social and economic disadvantage relative to the UK over the years. And as a Geordie, I might think to myself "oy, we don't all talk like that, you know" - but I wouldn't (and don't think anyone else would) argue that it ought to be deleted.
All of which is to say that I think we need to retain the ability to judge reports of this sort of thing on a case by case basis; a blanket rule could back us into a bit of a corner. We absolutely agree, however, that national prejudices exist, and we'll bear that in mind when looking at relevant reports.
