Does the Gaelic at the bottom imply that these are 'Irish jokes', written by and for Irish people?

My own Irish Mother always defended Irish jokes as (so she said) Irish people themselves enjoyed them and liked to tell them themselves amongst themselves - I know she certainly found them a hoot anyway. And I've heard older uncles deliver them pretty well too. She said the Irish thoroughly reject being cast as 'victims' of racism, by well meaning English people. It was a case of "Get off my feckin' side!".

I don't know how representative of broader current attitudes amongst Irish people towards Irish jokes, that opinion would be of course.
