So all "real" jews is zionists (a rather socialist philosphy born of revolutionary times and backed by Stalin in '48)? Also, Israeli politicians must be stupidist people in the world if they think that one grandparent Right of Return will bring in only well blooded or fully religious Zionists to Israel. No the real reason of the law was to bring as many none arabs with any amount of Jewish blood...whether Jew of Russian by nationality as possible...as Arabs out breed Jews like nuts.
By the way, most Hisidics and Orthodox Jews not in least Zionists...why? Because Zionist is nationalistic not religious and most peoples living on Kabutzies atheists.
