They live there because they immigrated through new York and settled down in New York. That doesn't mean they're required to integrate with the modern world, as much as that attitude disgusts me.
My issue isn't what they do in their congregations and communities, but how they interact with the rest of the world. I've personally been treated extremely poorly by strangers in the Orthodox community just going about my day in the city. Between that and other experiences, I'm just shocked at how prevalent racism is among the Jewish Orthodox community in particular.
