What type of common tradition between Jews of Yemen with their Qat in their mouths and Beber Jews with their Saksaki food and Flasha Jews with their jungle drums and Indian Jews with their Lungi dress and Russian with their Vodka ??
Different peoples in race , culture and language but they share on religion "Judaism "and this apply on Christians and Muslims plus Buhddists and other religions .
I can not understand the term Homeland as you are repeating it in every post ? Do you mean they were from one tribe or forefather and spread all over the world ?
Of course Jews from different parts of the world have many differences, but they also share qualities, including linguistic and cultural ones which are unique to them. Ethnicity and culture are fluid things, far from the way you present it.
Jews are very dynamic when it comes to culture and ethnicity, they are very diverse within their collective group, but they also share distinct ethnic traits, some would say even genetic.
ethnicity is 'measured' by cultural factors such as language, or even religion.
Contrary to what you try to say here, ethnicity is not simply 'race'.
Jews in Israel come from various parts of the world, but they all speak Hebrew, share Jewish traditions, heritage, ideologies. Furthermore, there is a generation of Israelis today which is a mix of Jews from different parts of the world, mostly Europe and the Middle East, but they still obviously share Israeli-Jewish culture, in fact this is their native identity.
