Starting With A Definition

Antisemitism is a word that appears in the news, in history lessons, and in everyday conversations. But what does it actually mean?

At its most basic:

Antisemitism is hostility, prejudice, or discrimination against Jews, simply because they are Jewish.

This means it’s not about disagreement with an individual person’s choices or behaviors, but about targeting people or communities on the basis of Jewish identity.

One of the most cited definitions comes from the International Holocaust Remembrance Alliance (IHRA):

“Antisemitism is a certain perception of Jews, which may be expressed as hatred toward Jews. Rhetorical and physical manifestations of antisemitism are directed toward Jewish or non-Jewish individuals and/or their property, toward Jewish community institutions and religious facilities.”

Breaking Down the Definition

“Perception of Jews” → Antisemitism often begins with distorted stereotypes or conspiracy theories.

“Hatred toward Jews” → This may be emotional hostility, political scapegoating, or violent hatred.

“Rhetorical and physical manifestations” → It can appear in speech (slurs, jokes, online posts) or in actions (attacks, vandalism).

“Targets” → Not just individuals, but also Jewish institutions (synagogues, cemeteries, schools).

Forms of Antisemitism

We’ll explore these more deeply in later lessons, but common forms include:

Stereotypes: Associating Jews with money, power, or manipulation.
Conspiracy Theories: Beliefs that Jews secretly control governments, media, or economies.
Dehumanization: Portraying Jews as alien, demonic, or subhuman.
Violence: Attacks on Jewish people or institutions.

Why Definitions Matter

Understanding what antisemitism is also helps clarify what it is not.

Not every criticism of Israel is antisemitic (though it can cross the line).

Not every disagreement with a Jewish person is antisemitism — unless rooted in anti-Jewish stereotypes.

Accurate definitions help societies make laws, track incidents, and teach responsibly.

Key Takeaway

Antisemitism is more than just dislike — it is a system of prejudice, myths, and discrimination directed specifically at Jews.

By starting with a clear definition, we can better understand how it has shaped history and why it still matters today.
