what I find consistently in history is that people learn to hate jews because of something they percieve/experience jews actually doing. That is why it pops up again and again regardless of indoctrination. I doubt it would be a mystery to you why many palestinians don't like jews...right? Do you think they were just born that way? Do you think they just read too much Martin Luther? Maybe residual influence from Titus of the roman empire? Or is it much more immediate...like jews killing them?
