“My truth doesn’t have to be your truth.”
Orthodox Jews have an extremely ethnocentric view. The laws and taboos have nothing to do with non-Jews. Why would they?
...In order to join Judaism, you need to be initiated, essentially acquiring Judaism as your ethnic identity. When a proselyte joins Judaism –after years of study and an extensive investigation examining their ability to keep the traditions — it is considered that our ancestors become their ancestors. Only by spiritually sharing these ancestors can a person become Jewish. Only by having Jewish ancestry can you worship the ancestral deity.
Interesting where you find similarities; Here I thought it was that we all landed in Brooklyn...
