To go back to the beginning: antisemitism, animus against Jewish people for the religion they profess and the community they belong to, is absolutely wrong, as wrong as any other bigotry. Trying to excuse antisemitic actions or expression by claiming to oppose the policies of the current policies of Israel offends twice. Using Israeli policies as an excuse to target Jewish people make them scapegoats for policies they did not choose and often do not support. Antisemitic acts and expressions by those claiming to advocate a just peace in Israel/Palestine cast doubt on the sincerity of peace efforts while obscuring the hard reality: more Christians than Jews support the bad political and theological ideas behind efforts to subjugate, expel, or destroy the Palestinian people.
None of this makes it any less important to report incidents fully and honestly.
