The Nazis wanted to eliminate anyone who opposed them, not just Jews. One trip to Mauthausen concentration camp -- which "housed" mostly non-Jews -- highlights that truth immediately. The Jews were only the first on the Nazis' long list of undesirables, which included millions of Catholic Poles, Slavs, dissident German Catholic and Lutheran people, Communists, Spanish Republicans, etc. The "selection bias" would eventually include hundreds of millions of people. Ironically, the Nazis would not include prostitutes, however, because there were brothels at most of the death camps for SS guards and their "helpers" (as they were at Mauthausen). Indeed, prostitutes (women "residents" forced into prostitution) were constitutional options for hard working SS personnel.
