This is a generalization. I'm from Algeria.. Saying Jews are "hated" is simplistic. In other countries? Maybe, I don't know.. Here? There's only a seeming anti-Jewish sentiment, but there's
way more to it than that: it's akin to estranged brothers than anything else.
You can notice it in traditions, in food, in music (have a look at התזמורת האנדלוסית הישראלית). Many Muslim musicians here used to go to the Synagogue because their friends playing in the same band were Jewish. And that's not that long ago, these people are still alive.
A bit back in time, Jews found a place to live here after being thrown out of Spain in 1492 because of the Catholic reform. To this day, there are towns with strong Jewish heritage. The "hate" you're talking about is only superficial, and only from the people who'd behave that way no matter where they are in the world.. Clothes have prêt-à-porter, thoughts have prêt-à-penser. Not all people can afford bespoke clothes and it's even more true with beliefs. They pick what's available, the easiest to wear, something not too challenging, not too far beyond the Overton window.
It's amazingly easy to talk with them and completely shatter that "hate" in 5 minutes. I've done it so many times that the pattern is clear. If it were hate, what I said would be so much against their beliefs that I would be attacked. Hate is not something you can shatter in 5 minutes, so this must be something else..
It's mainly lack of contact and communication that makes it easy to think that, somehow, Jews are a "different" specie. Once someone thinks they're a different specie, there's a feature void to fill, which people fill with their fears. I've been learning Hebrew and have corresponded a couple of times in it. I'm learning because of the culture but to tap into all which doesn't make the news: stuff regular folks do. There isn't a single one person I have told who hasn't been curious and intrigued about it and wanted to know more, or encouraged me.
Generalizations and simplifications are tempting because they work sometimes but this is exactly what I'm talking about. You don't like them because you think they don't like you, and they don't like you because they think you don't like them.
Everyday, conversations are taking place that address these issues and people are taking all kinds of perceptual positions. Hard questions that get talked about in groups of people who don't let you take the easy way out. People aren't dumb, despite what the media makes them look like.
And on that note, Happy Yennayer 2967. Today's the new year of my ethnic group.
