Who exactly is Irish?

I recently had an interesting discussion with some people about this topic, they were of different opinions, I will love to get a larger perspective on this topic.

Are Irish people strictly only descendants of the Vikings and the Celtic nation?
People with an Irish accent, who have an Irish passport?
Anybody with an Irish passport, irrespective of race, religion, gender, accent?
People born in Ireland?
Strictly white people?
People who have lived in Ireland for a very long time (like 20 years, though they weren't born in Ireland)
Or some other origin not explicitly listed here?

I am not of any particular school of thought or ideology, but I wish we can come to an agreement on who exactly is Irish, you can't say someone is Irish when it suits your narrative, then decide to switch and say they are Africans, Asians, immigrants, welfare scum etc when it does not suit your narrative

I have seen this play out many times in the UK, USA, France etc
The talented youngster who plays for Tottenham and England "Dele Ali", aaah he's British, born and brought up here, he is definitely not Nigerian.

Michael Olumide Adebolajo and Michael Oluwatobi Adebowale, the Woolwich stabbers in 2013, Hey mate, you see what I am talking about, all these immigrants they are bringing into the country, who don't share the same values with us, Nigerian scums, you see the effect of multiculturalism, you liberals and snowflake will bring our downfall.

One thing to note from this 2 examples is that they were all born and brought up in the UK, why do the criminal ones have to be linked back to Africa.

Anthony Joshua the heavyweight world champion is totally British, nobody talks about his Nigerian origin, same with Leroy Sane (man city) nobody talks about his Senegalese origin, he's German- end of story, but the other people who have a similar background but may not be as popular or talented as these individuals are constantly reminded to go back to Africa, or "where are you really from" questions

Salah, mane scores for Liverpool, yeeeaah he's a beast, GOAT, better than Messi, Ahmed stabs somebody in Abbey road Liverpool, F##k all this Muslims, lol

Recently Ireland won silver at the IAAF u20 championship, and the team was made up of 3 "black Nigerians" and 1 white Irish girl, though they were all born in Ireland, I saw comments on facebook, youtube, twitter etc which were so brutal, racist and hateful towards to the black girls who represented Ireland, they were called many bad names, including "Paper Irish" (named used to describe non-white people who have an Irish passport)

What do want from immigrants?
You complain that they are lazy and are all on welfare, then the ones who are highly educated and working, are taking your jobs?

You say they don't integrate into the society, then the ones who decide to date white Irish girls or men, are taking all the Irish girls, and some of you constantly stare at interracial couples with disgust (happens in almost all counties EXCEPT Dublin), and you say to yourself "they are definitely with them for the papers or money, giving birth to non-Irish babies".

What do you really mean by integrate? to play Gaelic football, speak Gaelic, eat Irish soup and potatoes, speak and write English, Obey laws and regulations, change their Religion and denomination to Christianity and Catholic, go the Pub and drink?

I will conclude this by saying, if you want multiculturism or "immigrants" you have to get the whole baggage, you will get the neurosurgeons, IT professionals and talented sportsmen and women, and you will definitely get the scumbags, who are assholes

No society is perfect, France won the world cup yesterday with many black players, USA NFL and NBA teams are predominantly black, nobody talks about immigration or crimes committed by black people, everybody is happy when they are winning.

Scumbags come in every race/ethnicity, country of origin, height, weight, religion.

Some people constantly look at everything through race, colour, country of origin, why can't we just get along well as human race, life is already too f##ked up for almost everybody.
