My children go to catholic schools - because I went to the same schools and had 14 years of utter bliss. So I wanted the same for them. Sometimes it really IS that simple. Integrated education, however, is becoming more and more popular. Most towns now have an integrated school. Even in the state schools, you will always find Catholic pupils. My own Catholic nephew was head boy in one!
You are guilty of seeing a few things about people here that you dislike, and applying them to us all. I am no unionist, but even I can see why they vote for the DUP. They are no different from any other group in history who was the privileged group - not one ever willingly gave up their privilege... just look at the suffrage movement, or the civil rights movement.
It is not often hatred that drives that - it is fear. Fear of losing their power and becoming the oppressed group. But more than that, this little country has had such a tortured, bloody history that people feel they are betraying their heritage and the people who went before them, if they turn away from how their community historically voted.
Look, I have no issue with the Republic - Connemara is one of my favourite places on earth and I will always be Irish, even though I am from the North and would like to be disowned by everyone My ancestral family has been on this island as long as your's have! They are as Irish as you! They went through the plantations, penal times (I live beside a Priest's Chair), Internment, the Troubles...and those things don't just melt away!
Our faithfulness to our own heritage is often at the root of all that goes on here.
Anyway, sorry for rambling - I was writing this while answering four children's constant questions at the same time so if it makes no sense you will know why!!!😀
