Combination of it barely being taught in schools and this weird contempt we have for our heritage. Ireland has put a lot of effort into preserving theirs. And they had Sinead O’Connor - she did a lot of the heavy lifting all by herself 😅

Same with languages. Scots Gaelic has all but died out in the highlands. Now its just a cultural relic and an annoyance. Search for news stories about the Gaelic road signs - they caused a massive stir.

Irish on the other hand - nearly died out but their government really pushed it in schools, the media etc. Poured real money into it. Its fairly widely spoken now.
