Part 2:
So, it is more than likely the people who were attacked and massacred by the Jewish people or Israel according to the Bible didn't much appreciate that, and those who consider themselves sympathizers with those people don't much appreciate what was done.
The Qur'an seems to condemn those actions as not actually commanded by God as the Bible claims it was. The following are not those verses though:
17:1 GLORY TO HIM who took His votary to a wide and open land from the Sacred Mosque (at Makkah) to the distant Mosque whose precincts We have blessed, that We may show him some of Our signs. Verily He is all-hearing and all-seeing
17:2 We gave Moses the Book, and made it a guidance for the children of Israel that they should not take another protector apart from Me
17:3 O you, the offspring of those We bore (in the ark) with Noah, he was indeed a grateful votary
17:4 We announced to the children of Israel in the Book: "You will surely create disorder twice in the land, and become exceedingly arrogant."
17:5 So, when the time of the first prediction came, We sent against you Our creatures full of martial might, who ransacked your cities; and the prediction was fulfilled
17:6 Then We gave you a chance against them, and strengthened you with wealth and children, and increased your numbers (and said)
17:7 "If you do good, you will do so for your own good; if you do ill, you will do it for your own loss." So, when the time of the second prediction comes, (We shall rouse another people) to shame you, and enter the Temple as they had done the first time, and to destroy what they conquered utterly
17:8 Your Lord may haply be merciful to you. But if you repeat it, We shall do the same. We have constituted Hell as prison for unbelievers
17:9 Verily this Qur'an directs you to the path that is straight, and gives happy tidings to those who believe and do the right: For them is a great reward
17:10 As for those who do not believe in the Hereafter, We have prepared a painful punishment
17:11 Man prays for evil as he prays for good, for man is hasty
17:12 We have created night and day as two signs, then We efface the sign of the night, and make the sign of the day resplendent that you may seek the bounty of your Lord, and know the computation of years and numbers. We have expounded most distinctly everything

It was far too difficult and strange seeming for all the Great Nations of the world to accept that an obscure tribe of people could be rightfully considered in any way better than themselves, and it was likely perceived as mere ethnic propaganda, perhaps even like that of other nations which may have praised themselves and their heritage. Many factors have led to the Jewish people being disliked one way or another today or considered "other", and when efforts were made in the past to integrate the Jewish people, radicals would try to separate them again, and these radicals are often celebrated (such as in the story of Hanukkah, and many other stories which celebrate events which are hostile to other people, people that are still identified with today, such as Syrians, Greeks, Persians, etc).
I was talking to a Jewish person who has tried, with great difficulty, to rid himself of self-identification as a Jew, after seeing that he not only believed in any of the stuff, but was also in a very tight community of Reformed Jewish people, some of who were Atheists like himself but were also very much of a similar or singular sort of communal mindset, from which he tried to escape. No doubt, some must consider him a kind of "Lost Sheep" or "Self-Hating Jew", but he didn't go in that direction, he just wanted to be a human being, to see past the prejudices that kept getting repeated within his community, which he described as a sort of "echo-chamber" of ideas. In doing so, he also learned that the Muslims are not the villains his community had generally accepted them to be as a matter of fact, and he could finally see all the racism, bias, and other things that were normal even underneath the words of the most Liberal seeming Atheists in his community which he was very much surrounded by and left ignorant about much of the "real world", and provided only a kind of simulation of it through the filter of his local culture and home life and relatives and their friends who were basically all Reformed Jewish people or Jewish.
The "Ghettoized" European Immigrant North African and Arabs might resemble in some ways the tendencies that may have occurred among the Jewish populations in earlier times, since any group of people who becomes segregated and alienated or even afraid that they may "lose their identity / culture" or "betray their upbringing" can lead to a sort of gang mentality and further stigma and inability to integrate well and general hostility. This has likely also occurred in Sikh communities where Sikhs sometimes end up forming a sort of Sikh Mafia. Muslims in Europe, much like people of African descent and Latino descent in some places, also formed tribalistic gangs and participate in criminal acts, and this was also something that some Jewish groups in the past had gotten into.

Basically, it seems to me, everything is mainly bad about exclusionary worldviews or supremacist worldviews or those which make any particular people separated, even if they are separating themselves due to some positive view, it always ends up somewhere bad one way or another, and shouldn't be done.
Even the way that Buddhist Monks separate themselves from the "Lay" population has created a lot of problems.
That is why "Universal" Non-Ethic religions became increasingly the trend, replaced now by Secular World Vision for a more United and Singular Humanity and Human Race:
Genesis 11:7 -
7Come, let Us go down and confuse their language, so that they will not understand one another’s speech.” 8
So the LORD scattered them from there over the face of all the earth, and they stopped building the city.9That is why it is called Babel, for there the LORD confused the language of the whole world, and from that place the LORD scattered them over the face of all the earth.
