Religious antisemites think Jews are bad because of their beliefs: They killed Jesus, they refused salvation.
Cultural antisemitites think Jews are bad because of what they supposedly do: They control the banks, they conspire against civilization.
Racial antisemitites think Jews are bad because of who they supposedly are: They have evil genes, they are not really human.
They are called anti-Semites.
Anti-Semites
Technically, the official term is Anti-Semitism. However, as the Jews are not the only "Semites," something like judeophobia might be a more accurate term.
They spread Propaganda, using stereotypes plus false accusations, accusing and blaming Jews for everything.

Hitler was one of the most rabid Anti-Semites in the history of the World. He did not only not like Jews, he not only hated Jews, he virulently despised and repudiated Jews.
It's exactly what it sounds like: Opposition to those who harbor anti-Jewish views and opposition the anti-Jewish views themselves. The difference between anti-anti-Semitism and Philo-Semitism (lover of Jews) is slight. A Philo-Semite usually makes proactively positive arguments (i.e. Jews are good because they win more Nobel Prizes per capita) whereas an anti-anti-Semite refutes anti-Jewish arguments (i.e. the racial theory of Judaism makes little sense when there are White Jews, Arab Jews, Black Jews, and East-Asian Jews). However, many anti-anti-Semites are also Philo-Semites because they will mix the positive arguments with the critiques of negative ones.
An "anti-semite" is one who hates Jews. "Anti-semitic" is what such hate is called.
Who are "Other Germans"? Other works only based on a referential. If "other" refers to individuals not directly affiliated with the Nazi Party, then you have a mixed bag. Anti-Semitism was quite normal in Germany prior to the Rise of the Nazis, but it was not something that would have led to mass violence without someone to instigate. Of course, there were also a minority of Germans (still large numbers, but a minority) who did not harbor any feelings towards Jews or actually tried to help them and sympathized with them.
It's a fancy word who people who hate and bait Jews.
Anti-Semitism is a hatred, revulsion, or denigration of Jewish people and a belief that those people are somehow (by dint of their genetics) more violent, conniving, mischievous, and dastardly than other people. In some cases, like the Nazis or Extremist Muslims, they are considered a "sub-human" race, on par with monkeys. Almost all Anti-Semites are not Jews for the simple reason that no person would willingly consider himself a putrid thing. Anti-Zionism is a rejection of Zionism. Zionism is merely Jewish Nationalism, the belief that Jews have a right to have their own country where they can determine their own future. Zionists can be both Jews and non-Jews and Anti-Zionists can be both Jews and non-Jews, because the question of whether the Jews have a right to a state is a political question. Since the Jews were able to create such a country, Israel, Anti-Zionism is usually seen as Anti-Israel sentiment. It is important to note that there are those who wish to argue that Anti-Semitism does not apply exclusively to Jews (since there are non-Jewish Semites), but the term Anti-Semite has never been used to describe anything but Jew-hatred. Additionally, people like to claim that Zionism is a code word for an international cabal of evil Jews trying to control the world. Aside from the fact that such a cabal does not exist, such a thing would fall under Anti-Semitism, not Zionism or Anti-Zionism since this cabal would not be concerned with Jewish Nationalism.
Judeophobia is a term which should replace anti-Semitism. I see it in action, and people who make nasty comments about Jews do not mention Semites at all.
