Most of the young people involved are recent immigrants from the former Soviet Union who possess only a small amount of Jewish ancestry. They are often rejected by other Israelis due to their predominantly non-Jewish blood as well as their inability to speak Hebrew. Focusing their rage on the ultra-conservative Hasidic Jews who they feel are most representative of their persecution, these pseudo-Nazis vandalize Jewish houses of worship and cemeteries, as well as run anti-Semitic websites. They members of this neo-Nazi underground obviously view Judaism to be a religion and a culture rather than an ethnic group, and so do not see themselves as being truly Jewish just because they have perhaps a single Jewish grandparent.
So much for the belief that intermarriage reduces ethnic conflict.
