Israeli Nazis?

I'm not sure how this makes any sense at all, but then we're dealing with crazy Neo-Nazis?

In Israel, eight immigrants from the former Soviet Union have been arrested in recent days for a string of attacks on religious Jews, gays, drug addicts and foreign workers. All of the suspects are in their late teens or early 20s and have Israeli citizenship. According to police spokesman Micky Rosenfeld, they all had "parents or grandparents who were Jewish in one way or another."

I don't know what to make of this or what to say about it. What is the point of attempting to understand madness?
