Earlier quoted context omitted.
Except, er, so since AIPAC has only be around since 1963 and the concept of Zionism over 100 years, that couldn't possibly be a reason why people have a problem with Jews? shrugs
I think the point being made is that antisemitism has been around for thousands of years, and the groups you're talking about have been around for 100. So they don't explain anti-semitism.
Assuming that OP hasn't been around for thousands of years himself, I could only point out modern day antisemitism which makes perfect sense. OP never asked for a complete history.
However, if you're going to get to the root of things, you'd have to bring up religious prejudices passed down through the centuries as well as the origin of money lending and banking which undoubtedly cast Jews in a bad light.
This documentary had some good examples as well as an overall interesting view of money itself: http://en.wikipedia.org/wiki/The_Ascent_of_Money
Edit: And this is now getting downvoted why? What the hell is going on here?
