Most Orthodox Jews I know prefer to spend most of their spare time with other Orthodox Jews. On the other hand, many of the Orthodox Jews I know prefer to have non-Jews as neighbors because they’re not as nosy.
From what I’ve seen, the more Orthodox and non-Orthodox mix, the more they hate each other.
From what I’ve seen, most non-Orthodox Jews have more positive views of non-Jews than they do of Orthodox Jews. Most of them would prefer to have gentile neighbors rather than Orthodox neighbors.
From what I’ve seen, Orthodox Jews make no assumptions about a fellow Jew’s ethics based on his level of observance of Jewish law. From what I’ve seen, increased observance of Jewish law does not make people more honest in business.
From what I’ve seen, non-Jews find it easier to deal with secular Jews than with Orthodox Jews. They prefer secular Jews as neighbors to Orthodox Jews.
Most people, most of the time, prefer their own kind. I notice that even in Orthodox synagogues, Ashkenazi Jews prefer the company of other Ashkenazi Jews, Sephardim generally stick with Sephardim, and Persians stick with Persians.
I notice that the more diversity people have to deal with, the more they keep their head in and their guard up. On the other hand, when people are with people like themselves, they tend to be comfortable.
When Jews move into a neighborhood or business, they seem to raise tensions (e.g., Postville) by challenging mores. The more observant the Jews, the more tensions they raise.
