When you find yourself living in exile, (in a culture opposed to your beliefs) you are tempted in 2 directions: conformity and isolation.
In conformity, assimilation works. You adopt the worldview, ethics, and way of life of the surrounding culture, and you experience deep change inside and out.
In isolation, you hedge yourself into closed communities where the culture can’t get in and your own culture can’t get out.
They are equally paths of ease. It’s easy to conform, and you’re richly rewarded for it. It’s also easy to hedge in and protect yourself and isolate.
But both ways lead to failures. Assimilation is a failure of nerve, and isolation is a failure of heart. Assimilation fails to resist; isolation fails to love.
