Racism was different in the 30s. Blacks Mexicans Arabs etc were basically not in western countries outside of mutt America and even then were treated as second class citizens.

Hitlers racism was about Jews and white people.
Hitler helped Jews by deporting them to Palestine and essentially giving them a state that way aka Israel.

When it comes to white people he hated most white people that were not German or maybe Nordic/British.

Essentially Hitler started a war with a white country against other white countries and caused mass destruction.

He also demonized anti semitism, racism and eugenics whist only really hurting whites. He hurt Jews but he contributed to them getting their own country.
