Answer:
Step-by-step explanation:
Wow that is some question.
I'm not sure the statement is entirely true (to start with). Many wars were fought between protestants and Catholics and the vocabulary used was religious doctrine. Today that seems silly, but the constitution of the United States protects religious differences (Amendment 1) and so that struggle is not nearly as important as it once was.
So -- Let's assume it is correct.
Anti - anything is really thoughtless. The actual question should be why do people hate? What is at the root of that? And why can they be stirred up to act on that hate? Why can't people take ten steps backwards and sit down and order a coffee? Why do people need someone to blame when things don't go right?
When you know the answer to those questions, Antisemitism is very easy to explain. Hatred, when it is organized, can turn on anything. It can create all sorts of trouble and a person like Hitler was a master of mob control and the channeling of hatred. He gave Germany a reason to blame the Jews and he did a terrific job channeling that hatred. It didn't take much to arrive at the Holocaust (although the campaign of murder had to wait about 3 years to get activated).
I'm not defending Hitler. I'm saying that Germany became his follower. He had succeeded where no one else had. I'm really talking more about hatred than I am Hitler.
