Pogroms, persecution and oppression absolutely happened. However it was mostly a new import from western Europe. Jewish citizens were second class but they were still “people of the book” and fared much better for most of the empire’s history.
However, understanding a bit more history there is a direct through line from those historical wrongs and the modern Palestinian genocide. It is just a continuation of the Spanish, Portuguese and British (amongst others) campaign against ethnicly semetic peoples that the Jewish people also historically fell victim to.
