This "Working Definiton" of "Antisemitism" Doesn't Really Work For Me

This is the definition that the 31 nations which belong to the International Holocaust Remembrance Alliance (IHRA) have settled on:

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.

You know that quip about how a camel is a horse designed by a committee?

That antisemitism definition, which is bizarrely phrased ("a certain perception of Jews"?), oddly reasoned (antisemitism can be "directed toward non-Jewish individuals"?), and which excludes any mention of Israel-hate, the Jew-hate of our era, is one honking big dromedary.
