What did hitler and the nazis say about jews, gypsies, and other groups it considered "undesirable? "

He said that jews, gypsies and other undesirable groups (slavs, disabled people) should all be eradicated or enslaved as they had no space on this world and should not exist. This is also the reason for his extensive campaign against all of the mentioned groups before and during WW2.

Imay be able to but what’s the question?
