Looks like it's just trying to be controversial. The Irish are fine, they have nothing to be ashamed of and lots to be proud of. Most of the world either doesn't know who they are or loves them.
It really is. As an American with some Irish, (if its a white from eastern europe it turned up on our dna test thingy) Im not sure if I or actual Irish people should be more offended.
I didn't establish a hierarchy of nationalities. It's like I'm saying it's bad to be Irish or Lithuanian in a moral sense I'm saying it's bad from the perspective of a Irish or Lithuanian person. Both Ireland and Lithuania are pretty shit tier countries and are very miserable places to live.
