This is about the Republic of Ireland, where that wasn’t a huge factor (there was definitely some; comments in the newspapers from 1961 when Dublin got a Jewish mayor are eyebrow-raising, but it wouldn’t have been a huge issue for something like this). You’re thinking of Northern Ireland.
That said, as I’ve mentioned elsewhere, Ireland in 1970 certainly did have other forms of discrimination which would’ve been much more relevant here.
Interesting enough, one of Israel's presidents was an Irish Jew - Chaim Herzog [0]. If you listen to his speeches, you'd think you were listening to an announcer on RTE [1].
This has absolutely no bearing on the article and it's content.
