If you read the text of the act, it really doesn’t do much of anything. Doesn’t expand the powers of the department of education or any law enforcement agency, just clarifies the definition of antisemitism used in existing laws about discrimination. The exact definition proposed is from the International Holocaust Remembrance Alliance:
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.
Nothing involving criticism of the government of Israel. That said, they do offer a little bit of clarification on their website:
Manifestations might include the targeting of the state of Israel, conceived as a Jewish collectivity. However, criticism of Israel similar to that leveled against any other country cannot be regarded as antisemitic.
I really don’t see anything worth getting worked up about. This is about as standard, boring government as it gets.
