Talking about Jew hatred.

Talking about Jew hatred.
Can someone please give a real, honest opinion as to why there is so much hatred of Jews?
For what reason?
How many of those haters have ever seen or met a Jew?
There are 14 million Jews world wide.

This seems to be something that has been handed down from father to child. But again, for what reason.
Are they not aware of what the Jews have brought to mankind, in the way of medicine, technology, science etc?
Can the 1.8 billion Muslims contribute even one grain of sand to compare with what the Jews have given to mankind?

hatred is the biggest form of jealousy.

The churches preach hatred of Jews

The mosques preach murder of Jews.
The Rabbis preach love of God and respect of humanity.

If the world religious leaders would follow the preaching of the Rabbis, then there would be peace in the world.
