Jewish has very strong family bonds but stingy to others.
I once dated a Jew. He pointed to me which section is lunch special on the menu.
Some other interactions with Jew were worse than that. They are very protective to their own people, quickly cover up any wrong-doings of their people and form a unified defence line. You will not win at all if you are alone to against them. They lie to protect each other. A really hurtful experience.
