One thing to add from way back is that Jews in many European countries were specifically courted to come to areas to enhance the finance and business community by giving them special privileges like a specific area that was kept Kosher, the Jewish Quarter of cities, important as pork was widespread in Gentile diets among other non-Kosher practices, while also being exempt from taxes and 'citizenship' which effectively was an obligation to pay taxes and fight in wars if called by the king or various lords. This bred resentment in addition to all you mention above, especially given the practice of using Jews as tax collectors. Usually in medieval societies there was limited contact with Jews outside of commerce, money lending (which might involved high interest rates as allowed by the laws of the time), or tax collecting, which generally did not breed positive feelings when the only contact was formal and often unfriendly.

Later of course cultural integration and intermarriages meant there was social connections outside of those formal arrangements that existed pre-modern era, but the built up prejudice and bigotry over hundreds of years, fostered by religion and often active efforts by local rulers, meant that even as society moved beyond the old reasons cultures in Europe became anti-semitic those transmitted prejudices were carried on from generation to generation, especially in areas where Jews were generally not common, like the smaller towns and countryside, as peoples' only knowledge of Jews was negative stereotypes, rather than real human interaction. For instance in Berlin, where the majority of German Jews lived by the 1930s, it was a generally anti-Nazi city due to most people actually knowing Jewish people and having positive experiences, while the smaller town folks, like Hitler and Himmler, who grew up in rural areas and had limited exposure to Jewish people socially, but got a large dose of anti-semitic rhetoric, were the rabid anti-semites that drove government policy.
