>>>This writer is wrong to lump all these Nazi victim groups together, as if their fates were all the same. Auschwitz was predominantly used for the mass murder of Jews. The Nazis didn’t have a genocide program against any other group.
The Jews were the target of the Final Solution as a group, ie., a genocide. Very true. But, the author was absolutely correct to include Gypsies, homosexuals, disabled persons, and others because they were included and yes, they were at Auschwitz as well as the other camps. Matter of fact, the very first targeted people were anyone with military background. For those people were feared to stand up and say no first.
They were all sorted by the codes on their arms as to what class, group, religion, level of work code, medical experiment, etc. codes provided by IBM.

IBM and the Holocaust
The first group sent to camps were the political dissidents. The first camp was Dachau in Germany, well before the onset of WWII. The most deaths occurred in camps in Nazi occupied Poland, and of those, Auschwitz accounted for by far the most - about 1,500,000.
