Here is my translation of most of the poster. Additions for the sake of style and understanding are included in square brackets:
With the assistance of Heaven
Our Daughters Are Given Over To Another Nation
A Revelation of the Opinion of Torah
The foundation of the subsistence of the nation of Israel is dependent upon the differentiation of Israel from the gentiles - and in particular the prevention of assimilation and intermarriage, Heaven forbid. Any relationship between a Jewess and a gentile man or a Jewish man and a gentile woman - whether it is willing or coerced - is a most serious blow to that Jew or Jewess and the entire Jewish nation. And it constitutes a desecration of holiness and is a betrayal of God that has chosen us (Maimonides, Laws of Forbidden Relations).
In a fit situation, when the nation of Israel has proper leadership according to the Torah, and when "the Israel's hand is strong" in our Holy Land (Laws of Idol Worship ch. 10), the leadership acts, first and foremost, to guard the holiness of Israel and "to be separated from the impurity of the nations of the land" ( Ezra 6:21), and the daughters of Israel can walk without the fear of dangerous contact with gentiles.
To our dismay, the present government in the Holy Land does not act for the purpose of Israel's holiness. On the contrary, it strives for "equal rights" for Jews and gentiles. And by this very definition it is interested in the intermingling of Israel and the Nations.
When there is no leadership that deals in practice with these problems - a situation is created where people feel abandoned to danger, and in a natural way they get up to defend themselves and their environs.
In the Pisgat Ze'ev neighborhood, as in many other places, in the past few years there is a phenomenon of Arabs that wander about in the streets and shopping centers, and they harass the daughters of Israel with impunity. Two weeks ago, young Jewish men that could not stand this disgrace arose, and acted resolutely against the Arabs. A number of the young men were arrested, and now the Police requests to lengthen their imprisonment until the end of [the judicial] process.
WE CALL UPON THE PUBLIC TO SUPPORT THE PRISONERS AND THEIR FAMILIES WITH ALL THAT IS NEEDED.
Of course the fundamental, deep-rooted repair will only be the establishment of PROPER JEWISH LEADERSHIP, like Ezra the scribe at his time that dealt with the purification of the pedigree of the nation of Israel, with the separation from the gentiles that were in the land and their removal from the land in order to fulfill the Divine precepts:"Do not give them encampment...Do not marry them.(Deuteronomy 7:2-3).
