Very easily.. Irish people are white
Of course, the objections to this are manifold and I'm used to them, from the EMJ nonsense to somehow an immutable characteristic of ours means we've lost our identity
Well, yes. I've already said that Irish people are white--at least they always have been, this is what I meant when I said
traditionally.
The identity part is more complicated. Part of that is genetic, a bigger part is culture and as I have said many times before I believe culture is the most powerful force in existence. Even the Romans knew this. It didn't take them long to figure out that they were far better served in terms of stabilizing conquered territory and stymieing rebellions by puppet ministries and governors appointed from endemic populations as opposed to standing armies. Turns out, the average Joe sixtooth doesn't really care who the insect overlords are so long as they can go on speaking their language, enjoying their customs and traditions and worshipping their gods and eating the foods they like and dressing a certain way etc et al.
My main criticism of leftism when t comes to immigration is that it's essentially magic dirt theory. The idea that you can just import people from alien cultures and somehow, magically, by some mystical property of the fields and the skies integrate. They don't, they form enclaves, and this always leaves to conflict with the parent culture. There's no better example of this than Islam. There are some exceptions to the rule, though.
I certainly agree with you that an immigrant from England, Scotland or Wales is going to fit in far better than a Somali. I'll also include Italians and Greeks. Basically any European.
I don't think the main battle to preserve Irish identity should be fought exclusively along genetic lines. Forgetting the fact that it's just too late for that, it is in the end culture that defines national character, laws....everything. Irish culture is what must be fought for. First however, all the illegals need to be deported, immigration needs to be slowed to a drip, and any immigrant who runs afoul of the law must be deported. No second chances. That, and the Government needs to start working for the people.
