ALL the Europes can now enter through our toll free borders Europe of the free market, Europe of fundamental rights, Europe of unhindered movement, Europe of vastly different, cuisines.
Welcome to you all; but, there are other Europes waiting to shuffle in the Europe of racial hatred and bizarre animosities, the Europe of folk pride, the Europe of ancient tribal rancour.
Those Europes were named by the vile Jean Marie Le Pen last weekend, and now stand at our doors: it is the Europe of nationalists: Euronat.
We are changing in Ireland, faster than we know. We are part of a multinational, multi ethnic political union, in which there is no control over population movement. We in Europe live in a single house; and that house is only as strong as its weakest lock - and in the cases of the eastern and southern borders of that union, that is not strong at all.
The movement of races from the poor East, from Maghre countries, from black Africa into the vast prosperity of Europe is going to change the complexion of our cities and, in due course, our towns and villages.
What is evident in Marseilles and Rome today will, sooner or later, be evident in the towns and villages of Ireland.
It is already happening in Dublin. The black and brown populations of the city, which until recently were confined to students and middle class professionals from either Africa or Asia, have dramatically increased over the past couple of years.
Dramatic Change
Dublin is rapidly becoming a racially mixed city. Within a very few years we should expect a large population of black Irish children in the capital, with other urban centres following that example. How will we cope with this dramatic change in what is religiously, ethnically and culturally the most homogeneous people in the EU?
There isn't a great deal of evidence that Irish people are more tolerant of other ethnic sectarian groups than people from other cultures; though the ideal of tolerance is widely held to be an Irish characteristic.
In the absence of any test of that tolerance in an Irish economy which was so backward that not even a Bangladeshi would come here, the ideal remained an abstract piety.
But now we have an economy repeatedly growing more quickly than we are able to predict we are going to draw immigrants from other cultures, with other values and other expectations than those which exist here.
Irish people going abroad did not abandon their church, their devotion to the family, their interlocking tribal pieties; and though the descendants of Irish migrants to England called themselves English - which is what they are - the Catholic Church they largely introduced England's cities is now the most vibrant Christian Church on Sunday, attracting more worshippers than does the Church of England.
It is exceeded in its attractiveness for the faithful by one other religious grouping in England: Islam.
In Abject Apology
So we must expect newcomers to Ireland to do we as the Irish did, and to arrive here with every intention of retaining their cultural norms and, religious beliefs and marital taboos.
They will not arrive in abject apology, desirous to abandon what they hold dear, and anxious to embrace the diminishing pieties of Irish Catholicism. Muslims will remain Muslims. Rastafarians will remain Rastafarians.
Habits, loyalties and tastes acquired on the Indian sub continent, in the souks of the Maghreb or the shanty towns of Trinidad do not vanish the moment visitors pass the Cead Mile Failte sign at Dublin Airport. They might become loyal citizens of Ireland, but we would be fooling ourselves if we thought that within a wave of a welcoming wand the new Irish will be culturally Gaels.
How tolerant will we be, especially when recession returns and jobs vanish?
It has been unpleasant enough to hear of the English born children of returned immigrants being bullied in school and called "Brits" by their peers. Can we expect to hear of similar abuse of children of Pakistani, African, West Indian origin?
Obviously, one hopes not. But the engine of tribal feeling is not to be found in newspapers for well meaning and well heeled liberals, such as this one. The engine for tribal feeling is in the school playground and the dole queue, the football crowd and the shuffling poor at the hack of the church.
Those engines function in all societies throughout Europe, and when that tribal discontent begins to simmer its warm rages engulf otherwise decent, law abiding people, whose lives might well have been have been radically transformed by immigration or the problems which it inevitably causes.
These people are the ideal fodder for the Euronat fascist revival which is occurring across the EU and beyond.
It almost passes belief that the recent National Front rally. In Strasbourg at which Le Pen baptised Euronat could have received fraternal greetings from Vojislav Seselj, the butcher of Bosnia's Muslims.
No more evil creature exists in Europe today; yet his greetings to his "fellow Christians", like other anti Muslim sentiments from Greek fascists, were warmly applauded.
Selective Perception
We are no more immune to the pulse of the tribe than any other species.
The trade union Mandate, recently condemned the British government for not releasing Roisin McAliskey on bail because she was pregnant: I very much doubt that its members have passed the same resolution in the case of Michelle Thompson who, like Roisin McAliskey, was pregnant while on remand on a terrorist charge.
Thompson was a loyalist awaiting trial on a charge of murder, arising from the death of a Catholic woman, Ann Marie Smyth, and a union such as Mandate would never have passed a motion in her support - for one of the keys to tribalism is its selective perception of victimhood.
The pulse of the tribe beats in Irish nationalist hearts as it does anywhere else. We will be just about the last people in Europe to receive large scale coloured immigration; then might we see how resistant we are to the toxins of the Euronat.
