It was not only the Jews who were persecuted by the Nazis. According to today.wmit.net: The T-4 Euthanasia program of the mentally ill and handicapped was another atrocity introduced by Hitler in Nazi Germany. It was established in 1939 for the purpose of maintaining the genetic purity of the German population by killing citizens who were physically deformed, disabled, handicapped, or suffering from mental illness. Selected victims were initially children, although later the programme was extended to include adults. They were executed by means of gassing, suffocation, injection, poisoning, starvation, or overdose of medication.
70,000 people had been exterminated by the time Hitler suspended the programme on 18 August 1941. The temporary halt was due to vocal protests from relatives of the victims, and churches. However, the programme was not terminated: it was merely carried out in greater secrecy. In all, about 200,000 people became victims of the T-4 Euthanasia programme before Hitler's attentions turned to the extermination of the Jewish people.

The Holocaust, the attempted extermination of the Jews and other groups deemed "undesirable" by the Nazis, was based on the idea that the Germans were the "master race." In every respect, it was a violent expression of discrimination.
People are sometimes persecuted for belonging to a certain ethnic group (jews are not only a religion but also an ethnic group; also negroes, other non-whites in many countries), other minorities or majorities (e.g., homosexuals, women, etc.). Basically, anybody who is "different" from what a group in power considers the norm.
The German Nazis fought for their beliefs just like every other group in history.
