It is not just what some Jews thought. It was becoming known that the Zionists planned to take over Palestine. This was confirmed when Britain landed with the Balfour declaration in its pocket.
All of the Palestinians actions were to defend their country from this planned takeover.
It's this kind of twisted, hate filled, xenophobic thinking about Jews that led to all the troubles in the region. How could the Arabs (which Arabs?) have known what the Zionists planned to do when there was no agreement among the early Zionists? There were nearly as many proposals as there were settlers. Some wanted a new Jewish state with the borders of the kingdom of David, which would have taken them all the way into Iraq, and some would have been content with a measure of autonomous Jewish government under British/League of Nations rule, and before that under Ottoman rule. The consensus that emerged, that the Jews must have a sovereign state of their own in the region, was forged in the fire of Arab intolerance of Jews and the violence it produced and the failure of the British to control it and to live up to their obligation under the Mandate to establish a Jewish homeland, not necessarily a state.
The Arab massacres of Jews in Hebron and Haifa in the 1920's had the same root cause, almost the exact precipitating cause, as the Araqb massacres of Jews in Granada and Cordoba in the 11th century, Arab intolerance of Jews, and it is just as much a core value of Arab culture today, as you demonstrate, as it was a thousand years ago.
"The 1066 Granada massacre took place on 30 December 1066 (9 Tevet 4827),[86] when a Muslim mob stormed the royal palace in Granada, crucified Jewish vizier Joseph ibn Naghrela and massacred most of the Jewish population of the city. 'More than 1,500 Jewish families, numbering 4,000 persons, fell in one day.'
"According to historian Bernard Lewis, the massacre - in Muslim narrative - is 'usually ascribed to a reaction among the Muslim population against a powerful and ostentatious Jewish vizier.' Muslims' sentiments of resentments of refusal of Jews to be subjugated by Muslims as Dhimmis can be seen in the following..."

The 4000 Jews in 1066 weren't murdered for stealing Arab land and water, and the hundreds of thousands of Palestinian Arabs murdered, maimed, and displaced by "creeping annexation" and "creeping transfer" since 1948 weren't trying to subjugate their new Zionist neighbors either.
Today's Arab majority in Palestine is reacting against a Zionist land grab that has been going on for almost a century; dunam by dunam, always arousing as little notice and resentment until all of historical Israel is under Jewish rule. Since there are not enough Jews on the planet willing to live between the Mediterranean Sea and the Jordan River to allow a Jewish majority, Israel will have to choose between existing as a Jewish state or democratic one. Religion has less to do with the demographic problem than greed does.
