there is a world of difference. Judaism places man on the highest pedestal possible "In the 'image' of God He created man" (Genesis 1:27)
Nazis viewed Jews as vermins and pests which must be exterminated.
Likewise in Pirkei Avot chapter 3 regarding all of mankind:
Rabbi Akiva used to say: Beloved is man that he was created in the
image of G-d; an extra love is made known to him that he was created
in G-d's image, as it says (Genesis 9:6) "for in His own image G-d
And continuing there, an extra status on top of that for Jews:
Beloved are the Jews that they are called sons to G-d; an extra love
is made known to them that they are called sons to G-d, as it says
(Deuteronomy 14:1) "You are son's to the Lord your G-d." Beloved
are the Jews that there has been given to them the precious
instrument; an extra love is made known to them that they were given
the precious instrument of the world's creation, as it says (Proverbs
4:2) "For I give you good precepts; do not forsake my teaching."

"I testify on Myself heaven and earth, whether man or woman, whether
gentile or Jew, whether slaveman or slavewoman, everyone according to
his actions, the Ruach Hakodesh (divine presence) will dwell on him".
(i.e. anyone can reach Ruach HaKodesh even women, slaves, or
