What did Jews ever do to get so much hate?

Your question implies several assumptions that are probably incorrect or imply an answer that doesn't exist.

First, do Jews get more or less hate than other groups? The history of man is full of war and persecution and injustice. How do you quantify hate? If you could, were Jews through history more or less hated than Romans? Mayans? Egyptians? It isn't possible to say. Mongolians conquered much of the known world and subjugated many peoples, were they hated? more or less? Some ancient South American cultures were bloody and violent. Did the subjects of those cultures 'hate' their leaders or the circumstances in which they lived? Did they hate the Spanish that conquered them? Did the Spanish that conquered them hate the people they conquered?

These are strange questions. There are many other motivations, more realistic, for why one historical people did something to another historical people. Hate is rarely the best answer.

And then, to say that Jews are probably the least violent of the Abrahamic religions - how do you quantify that? Per person? In total people killed or wars waged? Only in 'official' wars and sanctioned violences or do domestic issues count? After all, Jews are also probably the least populace of the Abrahamic religions so if volume is the only metric... you see how strange this question is as well?

I suspect that there is little or no difference, in the grander scheme, between Jews and any other peoples. Humans are humans and have a heck of a lot more in common with each other than a few superficial cultural differences might distract from. All people have been violent towards others and have suffered violence from others all through history. No people have been exempt from that.

If you are asking about current tensions or more recent issues then a historian might not be the only source you should seek an answer from. You might also solicit answers from theologians, political scientists and sociologists, to start, to get a more complete answer.
