The Irish government made the retarded decision to force Irish schoolchildren to memorise poetry in the Irish language without teaching them what it meant, nor explaining the grammar of the Irish language. This gave most Irish students a distaste for the Irish language and when they had children of their own they were less likely to introduce the Irish language to their children.

There are Irish people who converted to Protestantism and Ulster-Scots who remained Catholic, there were also Ulster Protestants who considered Ireland as a part of their identity. The same applies for the Irish Republic, prior to the 20th century most Irish people just wanted home rule, to have their own devolved parliament, it was the brutal suppression of the Irish uprising that turned Irish nationalism from a fringe ideology to widely-supported cause.
