I certainly don't hate Jews..............far from it. But to deny that there is a faction of the Jewish population in Israel that are anit-Christian is silly. Those Jews who do such are in the minority in Israel. To deny their existence would be the same as saying that there aren't any people in the US who hate Jews..........or in Great Britain........Prejudice is universal.
As you point out Anti- Christian attitudes in Israel are rare. What there is was built by inquisition, crusades and Progroms (in eastern Europe); and by failure of those of us who don't support anti- Jewish sentiment to distinguish ourselves.
Even among the few Jews with anti-Christian bias, very few would use vandalism to express their feelings.
I consider the report extremely suspect unless or until I see concrete evidence of Jewish participation.
