Insularism in a sentence as a noun

The kids were super passive aggressive to an outsider like me, but there was absolutely no violent bullying, and the insularism of the community meant I could just ignore everyone and they ignored me. Fundamentally though, its systemically broken to stuff kids in grades like this, with the same peers, with no escape for over a decade.
