Reading and debating on this thread I started yesterday about the all-Irish naming policy possibly coming into Fingal I have been struck again by the anti-Irish language attitude some have. But hardly any of them are West-Brits. They are more Anglo-American culturally and probably don't have many if any distinctive Irish traits but they are probably more influenced by American culture than English culture (although ironically on the matter of naming residential developments we have been influenced a lot by strict English culture). If they don't like the Irish language or don't think that it is a desired language generally I would say that they are not true gaels. You don't have to speak fluent Irish to be a true gael in my view (and I am not even totally fluent either) but I think that if you don't like the Irish language and do not consider it desirable to be able to speak it and you are Irish that you are a gall. You could say a colonised Irish person except that today you are colonised by Anglo-American culture as distinct from Anglo culture. So perhaps the term should be a 'gall Meiriceánach'?
Considering that the term West-Brit does not apply to hardly anyone in Ireland (even the English people in Ireland have more interest in indigenous Irish culture then the nihilistic Gaill Meiricéanaigh do) it holds no water when you throw it at people. So again, perhaps we should use the term gall Meiriceánach a lot more often.
