Now stop your mindless posturing.
If you can't see the differences between the immigration from Ireland and that from Mexico you must be blind. Hundreds of thousands of Irish came here, ten plus million Mexicans are coming here. Ireland is separated from the US by a large ocean, Mexico borders us. There was no way that the Irish could demand "Anschluss" with their homeland, but the Mexicans are a totally different situation.
Will we have to learn the same lessons as the Serbs did with the Albanians? They let large numbers of Albanians into their country as cheap labor, only to loose a large part of their territory to a Greater Albania. You are the underinformed one in this argument, not me.
BTW: I'm sure your wife will love Ireland, I've been there twice.
