Judaism is a religion as well as an ethnicity, sometimes it is regarded as one and not the other. Don't take my word for it. This is what Jews preach themselves.
How therefore can ANY data compiled about what Jews do or don't contribute in any diaspora context be remotely accurate?
If Ethiopians, Eskimos, and Indians can do "aliya" despite being racially nothing like ashkenazis, sephardim or mizrahim, then wtf are you even blabbering on about with these generalisations about "race"?
Europeans like you simply have no clue how to define Jews. Or perhaps you do and are trying your utmost to insert your personal narratives here.
