Coin clipping, no loyalty to the host country, blood libel, poisoning wells, opening gates to foreign enemy forces, usuary, although that one can be blamed on Christians who thought it was okay only if someone else did it, communism, pornography and prostitution, pushing feminism, homosexuality and transgenderism, funding both sides of wars, domination of the media. Betrayal to claimed allies. Invading Palestine and stealing more land illegally with settlements. Should I go on?
Now, I'm not saying I believe any of these obvious anti-semitic tropes with no possible connection to reality that happens but I'm telling you what others believed and caused some disagreement.
