I can't tell if you're just supremely ignorant, or something much worse. Denying the massacres, torture, and property seizures that Sephardi Jews encountered en masse between 1391 and 1492 is denying history (not to mention the expulsion in 1492, which directly caused thousands of deaths in transit, and the Inquisition thereafter of conversos who secretly practiced Judaism). It is on par with denying the Holocaust. Learn your history.
