The problem we all see is that you're saying that you are Irish. If you weren't born in Ireland, your parents weren't born in Ireland, you don't speak Irish, you don't pay taxes in Ireland, you can't vote in Irish elections, you wouldn't join the Irish military, you don't understand Irish culture, or know anything about Irish history, then in what way are you Irish?

You're not. But you have redefined "Irish" to mean something else. And that's what pisses people off. There are actual Irish people out there. Invent your own identity.

But you're not. You're American, with Irish heritage. You were born in America to American parents. You are super welcome to learn about Irish culture, about your heritage. You are super welcome to visit Ireland, visit the place of your fore-mothers and other ancestors. You can enjoy Irish culture as much as you want. Learn riverdancing and blast Michael Flatley all day long. You can even enjoy the bastardised commercialised version that is the totally fake US retail holiday "St Patrick's day". Wear some tacky green beads, put on a green hat, drink fifteen pints of Guiness! Sláinte! Have fun!

The one thing we're specifically asking you not to do, is to call yourself Irish. That's the only thing we're gatekeeping. You're Irish-American. You have Irish heritage. You have Irish ancestors. You have Irish family heirlooms. But you're not Irish.
