I take it that you never read the article, because otherwise you would have known that Jew hate does not go back centuries, but thousands of years. I suggest you read the article. It has nothing to do with the fact that Jews proclaimed themselves the chosen people.

I also take it that you have never read the bible.

Deuteronomy 7: Israel, you are the chosen people of the LORD your God. There are many nations on this earth, but he chose only Israel to be his very own. You were the weakest of all nations, but the LORD chose you because he loves you and because he had made a promise to your ancestors.

Jews have never spoken about this or boasted about this. It is only Christians who mention this, because they don't like what their own bible tells them.

Of course, there is no god, so it's a load of nonsense.

I suggest you read the article where it explains deicide and the Roman Catholic Church to you.
