I might be biased towards individualism but isn't the story of the Jewish people one of impressive individuals achieving incredible success while on their own, only for horrible things to happen as soon as large groups of Jews come together?
From Moses and Jesus to Einstein and Mises, some of the greatest men in history but from Babylon and biblical Canaan to the Holocaust and Gaza, unspeakably horrible things being done to and by large groups of Jewish people.
So what my confirmation bias is telling me is: Don't join the group - to achieve greatness you need only rely on yourself and your family.
