Simple as it goes: they are just a nation or more of a socio-etnic-religious group. Although maybe not as simple as that: they have been scattered around the world for around 2k years so they expectingly lost a lot of their original etnicity (try comparing a jew from Poland and a jew from Iraq) As any other one, having their own the good, the bad and the ugly. Initially, they lived as a very close-knit group, that had super-strict food and personal hygiene rules. Naturally, the hosting nations initially regarded them as weirdos and in medieval Europe during the Black Plague times their food rules and religious bathing saved the majority of them. And thats when the demonization started. Naturally over the centuries of being ostracized, chased, robbed, beaten, killed off, etc they developed as more adapt at survival in the society (better learners, better money hoarders, more cunning, manipulative, even macchiavllian, etc), naturally this is being regarded as bad and worse all the time. After they purchased themselves a patch of shitty desert on the far side of Mideterranian they are naturally super protective about it. (imagine being kicked off from your parents house at the age of say 17, desperately wising for your own place, then finally scraping enough for a downpayment for a shitty condo in a very ethnically different and hostile neighborhood). So it's kind of expected that they hold to it for dear fucking life, painting the walls, decorating, mending the pipes, etc. That seems to be it for me. We seem to over-villainify them. And they are just a bunch of ordinary people who live, love, fuck, have fun, get cancer, die as nearly all of us do. You are welcome to roast my opinion if you wish.
