They were saying all Jews from Russia (such as Ha'Gaon) are Gentiles who went to Israel for money. It's not something new they do, their existence is based on hatred for Ashkenazis (even though an Ashkenazi couple saved the life of that filthy negro Deri) generally and Russians Jews in particular. Deri smeared "filthy white Russians" of the Likud-Beitenu two weeks ago. And the music is Arab, the words are Arabic not Hebrew.
They were saying no such thing & it is in your mind that they attacked the Gaon.
I myself come from Jews from the former Soviet Union & am against the posseurs who are not halachically Jewish & many with no Jewish bloodline whatsover as are other Jews of Eastern Europe an heritage as well as authentic FSU born Jews.
Deri is a thief & a liar as is Eli Yishai but the ad is factual many Russian Goyim in fact those who are descendants of the pogromchiks slipped through the cracks & are only here for the benefits & many recieve quicky IDF conversions which are questionable by both Ashkenazi & Sephardi standards.
I did not hear the words of the song just the content of the ad which is more less a fact sans the fax machine.
I as a Jew agree with the content of the ad & I am sure most Jews that understand Hebrew do as well.
I do however question the sponsors of the ad as you do because Shas in general does not like Ashkenazim but it goes both ways.
Go to areas like Beitar Illit & see the tension between supposedly Chareidi Jews Ashkenazi & Sephardi this is what destroyed the Bait HaMikdash this what is preventing Moshiach from coming.
