You need to look in the James Murphy translation, which is one of two most accurate translation of Mein Kampf. This quote is not in Mein Kampf and is nothing more than western and jewish propaganda. The other translation is by Michael Ford, which is simpler to read but slightly less accurate. The two combined will give people a better understanding of the man Adolph Hitler and then you can move onto other books that tell a different story then what we were told
