Nazism isn't necessarily antisemitic, but totalitarian, race based fascism. Hitler didn't hate just the Jews, they were just the most convenient and plentiful enemy available in Germany at that time (we didn't have many black slaves in the country for example, plus the Jews were a tried and tested enemy due to widespread antisemitic tendencies in the christian population).

He also didn't care for most other races and ethnic groups and wanted them either to serve as a subservient class to the aryans (some eastern europeans for example), deport and "contain" them in their countries of origin (iirc most asian peoples) or, as with the jews, exterminate them by various means such as forced labor.
