Another thing that always confuses me is my own personal experience; I go to a high performing public NYC high school that has a large number of immigrants from South Brooklyn communities and Asians from Queens and South Brooklyn that you actually have quite a notable conservative population within the student body, even if liberals tend to dominate. My school is exactly the type of "feeder" school for these top colleges, and a lot of the top students are students from these conservative leaning immigrant families. Idk but the lopsidedness of college campuses always surprises me.
I can't speak for your birth cohort or the public K-12 students of NYC proper, but the shifting politlcal coalitions in the US and in other mature liberal democracies reflect a realignment away from the "liberal" vs "conservative" alignment of yesteryear. The issues the families of K-12 kids are more conservative on aren't always correlated with which ones are most important to how they vote.
This tweet describes what I've seen with Asians online and in real life, but I'd say it goes beyond socialization into the college+ population. (It's also true for African immigrant communities but I don't think people care as much since people generally don't think of African adult immigrants as a comparatively R group)
