Like many other parts of Europe, Ireland was itself colonized and need feel no moral compunction (no one else should either) about not wanting unassimilable immigrants, some of whom are deranged & violent. Almost all humans are tribal. Modern Westerners have been tricked into believing their tribe is ideological and based on silly morality. From Gaza, to Israel, to Ireland, to Minneapolis, we can see with our own eyes while using our own brains that ideological morality is stupid and brings more harm by far than good. It has always failed. ABN

Can you elaborate on that? What do you mean by Westerners believing their tribe is ideological and based on silly morality?
My thinking is that Westerners want to believe tribalism doesn’t exist, or if it does exist they certainly are not tribal, they are above that! So they want to get rid of whatever tribalism that still exists by destroying religion, culture, and tradition. Is this what you’re getting at?
I agree with you that Westerners are on a reckless, even suicidal path, regarding open borders and their denial of tribalism.
‘Is this what you’re getting at?’
basically, yes. replace practical nurture own culture with belief in magic soil. this was top-down manipulation, result of decades of infiltration and mind-control
