Good work by the other anons on some of the history, but as far as why Jews are 'hated', it boils down to the unwillingness of Orthodox communities to assimilate to the culture they exist around. An Orthodox Jewish community in, say, Belfast is going to be largely homogenous to one found in Bolivia. This is doctrinal...hence the 'Orthodox' term there. They frown on intermarriage as well, which has historically created problems in terms of genetic bottlenecking. This 'outsider' status has very often made Jews a popular target once unrelated civil disputes in the areas they live in come to a boil, and a convenient scapegoat is needed when an inconvenient reality won't suffice.
There is also the tendency for Jewish parents to be very strict/controlling and have high standards for their children, not being satisfied unless they begin a career in the medical, business, or theological fields. In many ways, it's the same stereotypes you find in Chinese communities, but without the shared religious culture.
In the Evangelical Christian community (since I can't speak for Muslims, which I've never had much experience with) there is a theological concept called 'eschatology' which deals with the End Times as interpreted through the book of Revelations. To sum it up briefly, this Christian subset with a very outsized political reach in the US believes that once all Jews are located in one spot (Israel) and killed, it will trigger the Apocalypse and the return of Jesus, which they see as a positive since they're under the impression that their belief will allow them to reign as kings and queens in what remains of Earth.
Also, most Jewish stereotypes were created by a Tzarist Russian screed called the 'Priories of the Elders of Zion' which pretended to be written in secret by a group of elite Rabbis, but was actually just the Tzar collating antisemitic lies together into a single book. I actually recommend giving it a read just so you can see how bullshit it is.
