It's not that they're alone in this; generally, friction between, say, very extreme Christian sects and the greater population is less reported on, because they are very isolated. The Amish don't bother anyone, but they also don't live in Brooklyn. Very observant Mormons generally keep to specific parts of the country.

These certain extreme Jews cause friction because they live very close to a really wide variety of people. They aren't isolated, but their culture is super insular. So the combination creates friction.
