And wouldn't Donegal be classed as one of "Ireland's Fenian pastures"?

The thing about being offensive is that, if you are saying something you believe in, in the way that is natural for you to say it, and it happens to offend people to hear you say it, that's one thing.

If you are saying something you don't particularly believe in, and saying it in a way that isn't your natural way, but is intended to be offensive to other people, that is quite a different thing.

Of course determining which is which is not too easy, and the person saying and the people hearing it might sometimes disagree on this point.

I think it's always best,if the ideas in what you are saying might be offensive to some people, you ought to avoid phrasing it in a way that could be taken as verbally offensive - it muddies the waters, and provides an excuse for them to avoid the real issue. One thing at a time.
