The Antisemitism Awareness Act has been approved in a 320-91 vote and will now head to the Senate. But the central question is: how and by what measure will federal authorities crack down on speech deemed "antisemitic"?

Will criticism of the government of Israel be deemed antisemitic? Will highlighting alleged war crimes or human rights abuses by the IDF be considered so? Will involvement in the BDS movement be deemed anti-Jewish? Will slogans such as "from the river to the sea, Palestine will be free" be illegal according to federal law? Will criticizing the US $3+ billion in annual foreign aid be considered anti-Jewish? 

And what of the many Jewish protesters who are engaged in speech condemning the nation-state of Israel? 

Already, active participation in causes boycotting Israel is 'illegal' in a number of US states (typically taking the form of prohibiting state agencies from engaging with companies involved in BDS).

According to an explanation of the definition of antisemitism outlined by the new House-passed bill: 

The bill would require the Department of Education to use the International Holocaust Remembrance Alliance's (IHRA) working definition of antisemitism when enforcing antidiscrimination laws.

The group defines antisemitism as "a certain perception of Jews, which may be expressed as hatred toward Jews" and says "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."

The organization provides a number of examples for what qualifies as antisemitism, including calling for the harming of Jews in the name of a radical ideology or an extremist view of religion, and accusing Jewish individuals as inventing or exaggerating the Holocaust.
