Who was Hitler against?

old answer

He was against the Jews and other people who disaggreed with him.

new answer

he was against anyone who was not aryan: this included Jews (who he loathed most of all), homosexuals, gypsies, the disabled. he also loathed other 'asocials' such as the homeless and drunks who did not appear in his vision of a 1000 year Reich.

he thought the slavic people were below the aryans and he quite respected the british for their power.
