Vince Dhimos answered a question at the German-language sector of Quora. The following is a translation of the question and Vince’s answer.
Why were and are Jews hated?
Before we start this discussion about hating Jews, we have to realize that there is a real and significant difference between Jews and Zionists. The Israeli government and the Zionists - including the American and European Zionists - have made great efforts to make the world believe that hatred of the Jews and opposition to Zionism are one and the same phenomenon. However, this is illogical for the simple reason that there are a growing number of Jews in Israel, the US, and Europe who reject Zionism and no one would accept the idea that Jewish groups might be anti-Jewish.
The reason why the Jews were hated in the distant past is not very clear. We do not have reliable historical records explaining the grievances on both sides, and we need to be careful not to fabricate our own reports out of whole cloth.
Much of the hatred of Jews in the past centuries is attributed to European Christians. There can be little doubt that often so-called "Christians" were to blame. For instance, Jews who refused to convert to Christianity in Spain could be burned at the stake. However, the word "Christian" has never enjoyed a consistent definition and it is hard to imagine Jesus approving of executing people for failing to accept Him.
If we define Christians as people who love friends and enemies, as Jesus taught, then we cannot blame Christians, but hypocrites who pretended to be Christians, but were not. Unfortunately, this way of thinking is generally considered a semantic game.
Ironically, most Protestant Christians in the US are "Christian" Zionists, but they do not follow the teachings of Christ.
They tend to give more importance to the Old Testament prophecy than to the words of Jesus.
For example, they influence political life in the US so that the political leaders they vote for give Israel arms to wage war against their neighbours. These weapons are sometimes used to kill unarmed Palestinian demonstrators and Iranian militias in Syria whose mission is to fight Wahhabi terrorists. The Israeli missile attacks in Syria even target domestic airports and endanger the lives of passengers. What happened to love thy neighbour as thyself? Judaism teaches this. It is from Leviticus. The "Christian" Zionists are Donald Trump's most important constituency, and thanks to them, the US is now flirting with a major war that has the potential to become a world war. In other words, there are significant numbers of both Jews and Christians who reject their own scriptures.
In addition, these "Christians" have been brainwashed by ultra-rightwing propaganda teaching that Iran, a Shiite country that rejects Saudi Wahhabism (the religion of ISIS and Al-Qaeda) for religious reasons, is the "biggest terrorist sponsor in the world." This absurd lie supports Israeli propaganda that Iran is a dangerous enemy of civilization. But in reality, Israel has 300 nuclear weapons (Iran has none!) and promotes war, causing the US to wage war against several countries. Countries that are not enemies of the US population.
Fortunately, Europe has not yet fallen victim to this religious fanaticism based on a complete misinterpretation of the scriptures.
Let me be clear: anti-Semitism is morally wrong and violates the teachings of Jesus.
But Zionism in its radical form teaches racism, and this racism led to the killing of countless innocent Palestinians by Zionist terrorists like the Stern Gang, Irgun and Haganah in 1948 and earlier.
The following is an excerpt I translated from the Spanish-language book, "Violencia y terror de los sionistas, antes y después del Estado de Israel", Editorial Canaan, and posted at Quora:
"Dr. Teresa Aranguren  reports in an informative book about the events that have taken place. I just want to highlight a few touching paragraphs from her book:
On April 9, 1948, Irgun and Stern (whose leaders included future Israeli Prime Ministers Menahem Begin and Yitzhak Shamir) carried out the massacres of the residents of Deir Yassin.
"A young man was tied to a tree and set on fire. A woman and an old man were shot. Girls were put on a wall and shot with a submachine gun. The statements of the filmmaker Neta Shoshani about the massacre in Deir Yassin are hard to understand even 70 years after the fact.
"The region's Red Cross delegate, Jacques de Reynier, was the first to arrive in this location when the [Zionist] Irgun militias were still present:" Among the troops were some very young people, almost adolescents, all in military clothing and helmets, men and women armed to the teeth with pistols, machine-guns, grenades and even big knives, most of them still dripping with blood. A very beautiful young woman showed me her blood, that dripped [from her knife] like a trophy...
"I went between them and entered a house. The first room was dark, everything was confused, but nobody was visible. In the next room I found several bodies under the furniture and the broken mattresses, which were already cold.
"The cleansing had been done first with machine guns, then with grenades, and finally with the long knives; they were not worried that they would be discovered. The same scene as in the next room, but when I was about to leave, I heard what I thought was a sigh.
"I moved the bodies until I touched a small foot that was still warm. She was a ten-year-old girl, badly injured by a grenade, but still alive. I picked her up and one of the men tried to block me at the door, I pushed him and left with my precious body ...
"We checked the other houses and found the same horrific scene in all of them. We only found two other people alive, two women, one of them an old woman, who had huddled in the kitchen and hidden there for hours ...
"The village had four hundred inhabitants, about fifty were able to flee, three survived, the rest had been massacred by order of the commanders, since they are admirably disciplined troops ..." 
"Jacques de Reynier cites the death toll of 347 from the murder of Deir Yassin. Other sources speak of 250. In any case, it is not about the number of victims - because in those months of 1948 there were similar massacres in many other villages in Palestine - but the echo that the murder had and the panic movement that it evoked that made Deir Yassin one of the keys to the exodus of Palestinian peasants.
[In my debates with Israelis and Zionists in Quora, I repeatedly encounter the argument that the Arabs had left of their own free will and that the Zionists were not responsible for their exodus. Of course, they never mention these massacres, which, as reported at Haaretz, is being systematically covered up by the Israeli government. What is the definition of evil? Vince]
"Indeed, one of the elements of military strategy has been to achieve the “spontaneous” evacuation of the Arab population in rural Palestine. One pattern that was constantly repeated was to surround the villages and send a message through loudspeakers to the inhabitants: leave the village, or you will suffer the same fate as Deir Yassin.”
Below is a link to a video that allows you to understand how the first Zionists got their “rights” to the land:
In light of the above, it seems that if the Israelis have a right to this land, the Arabs have no rights, not even the right to life, and the Israelis have the right to kill them with impunity.
That is the essence of Zionism, so the elites had better stop saying that Judaism and Zionism are identical! Because saying that is the height of anti-Semitism and it suggests that Judaism promotes murder, when it does not. The startling truth of the matter is that Israel has a shortage of Jews and a surplus of Zionists.
