Anyone familiar with why Southern Irish as a country predominately converse in English and not Irish?
I'd take a wild guess that it was all
The Invading,
The Conquering,
The Colonising,
The Subjugating,
The Anglicising of state and power for decades,
and the beating at school for speaking the native language wot dun it.
You undermined brexit yourself by not taking the GFA into the equation,don't blame Ireland for your own mess.
