While it is absolutely correct that things were generally worse for Jews in Christian Europe than under Muslim rule, the idea that live as a Jew under Muslim rule was always rosy or that Zionism was the reason things got bad is simply not consistent with history.
” we lived in far greater harmony under Arab rule than under the rule of any other country that hosted many Jews”
The United States of America is an exception to that statement.
Also, FWIW while the Jewish population of India was never large, Jews were never persecuted in India by either Hindus, Buddhists, or Muslims. Not sure why more Jews didn’t move there.
