Irish New Yorkers were being heavily discriminated against, to the point that worrying about rights, houses, and jobs was a particularly serious and somewhat unique problem for Irish folks (individuals!) there at that time. It’s not like someone fresh off the boat is going to be able to pass as anything else.
There were also prevalent crime issues and ethnic gangs at the time. And many people (Irish in particular) DID go around saying those things you assert no one ever said.
For people who ‘looked Irish’ it was absolutely in their interest to align with these groups to some extent, or they’d be discriminated against and not have useful power to fight against it, and not have a group of people aligned with them that would provide housing, jobs, etc. to them.
In fact, near as I can tell, the only reason the Irish stopped being discriminated against so heavily is because of the political machines and gangs that punished groups for discriminating against them this way.
I can see that we have different interpretations of what acts were central to the progress of civil rights, and which were ancillary or even effects.
I don't think, for example, the "mafia" was a major contributor to equal rights for Italian immigrants. One obvious piece of evidence is that today, the mafia has been weakened thanks to the efforts of the police, but Italians haven't become persecuted as a result.
Membership in the Italian Mafia has turned out to be bad on net for the good of the people the families claim to represent. I think some people can get rich doing it but it is not a beneficial or admirable lifestyle.
If you want another example, where were all the Jewish gangs? I'm not aware of a single one. Some famous gangsters were Jewish (at least if you count the movies, I don't know about real life), and I don't think the cause of equal rights has suffered as a result. You have to read this with a smile even though the topic is very serious because the ideas involved would be at home on Saturday Night Live.
One final example is what could be the most hated organizations in America: the white nationalist gangs that only exist in prison. They are all in jail, and equal rights for people of European descent hasn't suffered at all. I'm surprised I ever participated in a conversation where I had a reason to write this, but white nationalists have no positive goals, not even for anybody.
The advancement of the universal recognition of equal rights for all is a much better explanation because unlike the rise of gangs, it hasn't been reversed.
As to your second point, not all Nash equilibria are beneficial. Gang formation is a lot like a Keynesian beauty contest in that appealing to the basest parts of our nature is the safest bet, and I think we can agree that this has nothing to do with anything good.
People do not need to "band together to survive" in that sense. Those gangs were mainly shaking down businesses in their own neighborhoods anyway, and everybody is a lot better off now that they're history.
That is a rather weird shifting of the goal posts, and completely ignores that there is such a thing as collective interests if a collective is being specifically targeted, or has special interests correct?
Yes, collectives don't have special interests. Individuals have specific instances of universal interests, like security or freedom. "Black people" doesn't have a separate existence from a black person. By guarding the principle of equality before the law, you are not getting involved in anybody's business but yours.
It isn't right to view something like equality before the law as a matter of somebody else's self-interest, or to justify a ruthless pursuit of self-interest by recasting it as service of an imagined collective interest.

Same with the Catholics, actually.
So what are you actually talking about?
