they shouldn't object to registering English as Ireland's official language in the EU.
Firstly most Irish people do actually know enough Irish to speak it. Anyone who came through the Irish education system had Irish lessons every day from the age of four and in many schools Irish was spoken most of the time in class. However, after primary school the emphasis is on the written word and kids who generally love Irish in primary school begin to lose interest. The syllabus often involves very little conversation and a lot of reading rather depressing material about hardship, famine, emigration etc and writing of essays on same. Many people of the older generation associate the language with harsh teachers, scoldings, whacks with a stick or even a strap, failure etc. The language for many people became a tool of punishment and misery.
Once people leave school they generally never use their Irish again but, the interesting thing is, that if you drop them into a total immersion situation and normal social interaction for about two weeks, it comes back to them and though it's no more than basic to lower intermediate level at best, they can actually speak Irish and could be quite fluent if they kept going with it.
Secondly, there is a strange thing occurring, where the number of native speakers in the Gaeltacht areas where the people have retained the use of the Irish language throughout history, is now dropping but the number of urban speakers in places like Dublin is on the rise. The waiting lists to get into the Gael Scoileanna (all Irish language primary schools) are as long as your arm. Huge demand for education through Irish.
I personally think the way forward is to not have Irish as an examination subject as it is at present but have it as purely a conversation and culture subject with the music, dancing etc as part of the syllabus and the option for senior students in the last two years of secondary school to take an Irish language proficiency test if they wish to do so.
The language is a poltically sensitive issue for many complex reasons that also involve Northern Ireland so this is not the forum for that discussion.
