Even if you are 'part Irish,' you should be able to get basic English grammar at least partially correct.
I speak & write US English. And by online standards not too badly, when many today converse in cryptic text-speech.
But I wonder how you cope living in Chicago, where your pure Queen's English (or is it Irish English?) isn't spoken at all? When someone says they're going to put something in their car trunk, do you put on a quizzical expression because they didn't say "boot"? Do you wander around aimlessly in buildings asking for the "lift" because no one realizes you mean the elevator?
US and British English differ on many points, including grammar, pronunciation, spelling and vocabulary. I'll speak mine, and you can speak yours. But ARISTOshark may NOT fault me in his insufferably superior manner for a common US usage that's been around for centuries. And claim something's "always been" that way, when he's totally wrong.
I welcome friendly corrections, I enjoy learning. But I do not welcome pompous jerks with ARISTO in their screen names, attacking me from out of nowhere regarding something about which they are woefully uninformed.
And that's where you & I previously crossed swords, not the Irish themselves as you tried to morph it. And certainly not you personally, but over matters of Irish & English history which you had wrong. I tried to tell you I understand the Irish slant on these events, all nations have them, and used my own Irish family members as examples.
But instead you attacked me personally (and even my grandmother!), going so far as to say my Irish ancestors arriving in 1850s America were "whores" and no longer Irish because they weren't in Ireland anymore. After that I owe you no explanation nor apology for anything I say. You've got a big chip on your shoulder you need to work on removing, or you're gonna do a lot worse in the US than my fully Irish ancestors did.
