The correct answer is "anti-semitism".
Anti-semitism is the term used to refer to the exercise of hostilities or discrimination against the Jewish community, as in the case described in the example. It is a form of racism, and at certain moments in history it has been also a political ideology, as during the government of the Nazi Party in Germany, before and during WWII.
It is also a political stream followed by detractors of liberalism, as Jews have historically represented the figures of lenders, usurers, and have created rich communities which have generated envies and hates.
