the demonstration started with the Palestine-rights activists condemning the Israeli apartheid wall.

On the Zionist-racist side people were singing opera and dancing to kitsch songs. I think that they were trying to show their enlightened and sophisticated taste. Zionists often try to prove their “civilized superiority” compared to the “primitive” indigenous population of Palestine.
I was reminded of the writings of Zeev Jabotinski, a famous Zionist theorist who has influenced many of the leading figures of the Israeli-apartheid state (Ben-Gurion, Begin, Sharon, Olmert).

"We Jews have nothing in common with what is called the 'Orient,' thank God. To the extent that our uneducated masses have ancient spiritual traditions and laws that call the Orient, they must be weaned away from them, and this is in fact what we are doing in every decent school, what life itself is doing with great success. We are going in Palestine, first for our national convenience, [second] to sweep out thoroughly all traces of the 'Oriental soul.' As for the [Palestinians] Arabs in Palestine, what they do is their business; but if we can do them a favor, it is to help them liberate themselves from the Orient.'"
"We Jews, thank God, have nothing to do with the East. . . . The Islamic soul must be broomed out of Eretz-Yisrael. . . . [Muslims are] yelling rabble dressed up in gaudy, savage rags."
