Answer:
Antisemitism is anti-Jewish prejudice, discrimination, hatred, hostility, violence, or oppression.
Anti-Jewish laws have been a common occurrence throughout Jewish history. Examples of such laws include special Jewish quotas, Jewish taxes and Jewish "disabilities".
Some were adopted in the 1930s and 1940s in Nazi Germany and Fascist Italy and exported to the European Axis powers and puppet states. Such legislation generally defined Jews, deprived them of a variety of civil, political, and economic rights, and laid the groundwork for expropriation, deportation, and ultimately the Holocaust.
When young people witness or are the targets of antisemitism in their communities, they may feel isolated or more vulnerable. Those who are Jewish may become afraid to state or show their Jewish identity for fear that they will become targets of further antisemitic comments on social media and in person. Suppression of identity—being afraid to bring your whole self into your various communities—is one potential impact of antisemitism. Another critical component is how others respond to antisemitic behavior and actions.
