Yeah, well since the Jewish religion is so closely tied to the ethnicity of the people, the issue is very contentious.

The question of whether Israelis and Palestinians can be said to constitute "racial groups" has been a point of contention in regard to the applicability of the ICSPCA and Article 7 of the Rome Statute. Political writer Ronald Bruce St John has argued that in regards to the ICSPCA "Israeli policy in the West Bank cannot technically be defined as apartheid because it lacks the racial component". However he then states that with the 2002 introduction of the Rome Statute of the International Criminal Court "the emphasis shifts to an identifiable national, ethnic or cultural group, as opposed to a racial group," in which case "Israeli policy in the West Bank clearly constitutes a form of apartheid with an effect on the Palestinian people much the same as apartheid had on the non-White population in South Africa."[28
Also some argue that whether you're "Jewish" or not does indeed depend on who your parents were:

The HSRC's 2009 report states that in the Occupied Palestinian Territories, Jewish and Palestinian identities are "socially constructed as groups distinguished by ancestry or descent as well as nationality, ethnicity, and religion. On this basis, the study concludes that Israeli Jews and Palestinian Arabs can be considered 'racial groups' for the purposes of the definition of apartheid in international law."[31]
