Because they declare they are God's Chosen People, which is offensive
Because they do not integrating society making themselves an outsider minority
Because of religious reasons, ie "Christ killers" and ancient conflicts with Muslims
Because for whatever reason they tend to become wealthier than most people
Because they tend to favor each other in dealings unfairly
Because they collectively conspire to gain influence where ever they are
Their rituals and self-collectivism invokes xenophobia
Because Jews oppress people when they gain influence
Because Jews tended to surrender or flee rather than fight so are easy targets of hate
The poll is false. Historically Jews have not suffered atrocities more than others
Resentment and jealousy probably. They were a discrete community and were generally successful.
Declaring themselves "God's Chosen People" probably didnt do them any good, lol, but as a modern person, I laugh at such claims and dont take them seriously. People of the past? Hard to say how they perceived such a claim.
