Why did the Nazis dislike Jewish people enough to order the holocaust?

Answer 1

At the end of the first World War, the Allies forced the Germans to sign a peace treaty that many people (the US, for one) thought would cripple any chance of Germany's economic recovery and would destroy its political life.

That is exactly what happened, and the Germans - who had also trouble accepting that they had been beaten fair and square in the war - went looking for scapegoats for their defeat and for their economic and social problems. Pamphlet writers came up with the "answer": the problems were the result of an Allied-Jewish 'conspiracy' to keep Germany down: Jewish bankers and industrialists in America and elsewhere had conspired (they wrote) to make the World War 1 Peace Treaty as harsh as it was, and now they were making a fortune bleeding Germany dry.

Although this was nonsense, many right wing Germans chose to believe this, including the right wing parties such as the Nazi party. The result was that Hitler pledged to 'remove' the Jews from German society. For years he toyed with the idea to move them to other lands - Madagascar was a long-time favorite - but when he discovered that this would be impractical, he decided that killing them off must be the solution.

Answer 2

there are many reasons as to why they disliked the Jews, but you are wrong to suggest that their affinity was the reason for them perpetrating the Holocaust.

Like or dislike, they did not know the Jewish people, they just wanted a society without them, from this the Holocaust evolved.
