Learning to hate

It does not matter what you teach a child, if he open his eyes later on he will know the wrong from right. but it is most difficult to remove the feelings that we got as young kids from our personalities.
I learned to hate Jews (all of them .. Their group) like any body else in Arabic countries. I learned that in school, and in mosques etc..
Later on. I learned about Einstein, ostrakh and many others.. Learned about democracy and advanced researches in Israel.. Learned that less than 1% of the world are Jews but much more then that ratio when it comes to medicine, Music and others humanitarian branches.. So I stepped back and found out that I cannot hate them as group, but on the contrary respect and like them .. I am not talking about individuals that can be as bad as any individuals else where.
let's look at the other side.
They learn to hate Arabs/Muslims in schools and synagogue etc.. Later on .. They learn about suicide bummers and other achievements of this group.

Now let's take the third party .. They learn to hate both Jews and Arabs/Muslims.
they grow up later one and see both parties .. What would they think.??
