Interesting, but IMO that happened quite some time ago:
....[Bishop John Joseph Hughes] immediately stirred up a war over the city’s schools, then run by the Public School Society. Though the society received state funding, it was essentially a private Protestant organization that taught Protestantism and used the Protestant Bible. Worse, from Hughes’s point of view, it had pupils read such books as The Irish Heart, which taught that “the emigration from Ireland to America of annually increasing numbers, extremely needy, and in many cases drunken and depraved, has become a subject for all our grave and fearful reflection.” Hughes (with the support of New York’s 12,000 Jews) wanted an end to such sectarian education, and he wanted, above all, state aid for Catholic schools, just as the state had funded denominational schools before 1826 (with no one dreaming of calling such aid unconstitutional). The outcome of the struggle pleased no one: the Maclay Bill of 1842 barred all religious instruction from public schools and provided no state money to denominational schools.
-- from the article How Dagger John Saved New York’s Irish....1841 was an election year in the state of New York. Five days before the election, at a Catholic rally at Carroll Hall, [then-bishop John Joseph Hughes] presented his parishioners with a list of the candidates he favored for council and urged them to vote for them....
....The Constitution gave Hughes the right to advise his parishioners how to vote, but the Protestant establishment was outraged at what they saw as priestly meddling in politics. Leading the attack, James Gordon Bennett, editor of The New York Herald....
....Hughes's politicking paid off. All but three of the candidates he had supported were elected. In April 1842, the state passed the Maclay bill. By a majority of just one, New York's Senate voted to end religious instruction in New York's public schools....

I recommend that whole series. It’s available on Netflix.
What viewers will see, that’s missing in your snippet, is that the city’s public school students were being indoctrinated in anti-Catholocism.
