I'm actually like 50% Irish, born in Massachusetts, and I have no problem saying that:

1. Massachusetts imported the Irish so they could conquer the south in the Civil War, but for this they paid with their soul. Irish rule Massachusetts, and will for the foreseeable future.

2. Irish Americans don't give a shit about some white ethno-state and never will. Irish don't even give a shit about making Massachusetts not a steaming pile of shit. You give good union jobs to the Paddies and you get the votes, if you don't, you don't.

I have no reason to think Italians, Mexicans, etc are any different.

¯\_(ツ)_/¯
