The earliest example of this that I have found occured in late 1945. The Arab League, alarmed at the acceleration of the movement towards Zionist statehood, hit upon a formula that they have repeated many times since then - the boycott of Jewish products (sometimes called "Zionist" products, but as can be seen below, the word "Jewish" was used interchangably with "Zionist" at the time.)
Almost immediately, there were concerns among Palestinian Arabs about the impending boycott and how it would affect their livelihoods:
Of course, this doesn't stop the Arab leaders, who always know best. On January 1, 1946, the boycott starts as planned. Immediately, there are problems with compliance.
So, the wise Arab leaders decided to extend the boycott to not only Jewish goods but also to Jewish services. No longer could Palestinian Arabs go to Jewish doctors or Jewish-owned movie theaters! That will teach those uppity Jews! (Notice that here is one case where the boycott is explicitly called against "Jews", not "Zionists." The almost inescapable conclusion is that the Arabs were reading from the Nazi playbook, where boycotts of Jewish goods preceded the Holocaust.)
It is also interesting to note that the non-compliance by Palestinian Arabs here in late January is becoming more of a concern to the leaders of the boycott. Not that they were consulted or anything.
The months flew by and the boycott became less and less relevant. Palestinian Arab leaders passed yet another of their many anti-Jewish resolutions at yet another meaningless meeting in August, and called again for their people to abide by the boycott that was still being roundly ignored.
Meanwhile, the Jewish economy was booming as never before! As this October article shows, the Zionists adjusted their economic models to sell more to non-Arab countries. Any effect that the boycott may have had was more than offset by their business in new markets.
As 1946 became 1947, and as Israel became closer to becoming a reality, the Arab leaders refused to believe that the boycott was an abysmal failure. Someone had to be at fault - and that someone was, of course, the Palestinian Arab businessman who refused to go along.
The solution was simple. Bomb the Palestinian Arab businessmen!
Just bombing them in Jerusalem was not enough. This had to become a national event.
One at least one occasion, the targeted businessmen had had enough of this.
The only ones hurt were the ones that the boycott was officially supposed to benefit.
I don't know if this is the first time that Palestinian Arabs were treated like dirt by the people who pretend to champion their cause, but it was certainly far from the last.
