If you do that, you're being inaccurate.
The Nazis murdered about as many non-Jews as Jews.
They killed a much higher percentage of Jews than of any other largish group, but that was of course of little comfort to murdered non-Jews.
Roughly 2/3 of Jews in areas under Hitler's control died. About 25% of Roma. To pick two groups the Nazis hated the most.
I think Simon Weisenthal has said that about 11 million people died in the camps,about 6 million of whom were Jews.
Pentecostals: the only religious groups specifically singled out by Hitler for extermination.
