@Teddleshon, again, that is - sort of - true (but also: not quite, and not quite in the sense of "why Israel should be beyond reproach in 2023"):
First things first: "Jews" as such and in the sense that we know them today are a much younger construct - arguably! I am not a religious scholar, just a bored woman who reads a lot! - than what you might imagine! "I am the lord, thy god, thou shalt have no other gods before me" - these days typically taken to mean "polytheistic society and wider setting - just: this one deity, El, YHWH, Hashim (which just means "the name, actually), God, ... whatever as an atheist I really do not mind what people call it! demands primacy (not exclusivity)".
Did anti-semitism exist in classical antiquity? Oh, yeah, but sure! Neither Greeks nor Romans were particulary keen on Jews! But then, they were not on Christians either (pre-Constatine, at least). Their whole "thing", was, essentially: "religion as state" - which made them exceedingly tolerant towards any group that was happy, or at least grudgingly okay, to also pay lip service to the Graeco-Roman pantheon while doing [insert: whatever the hell you please!] as a main gig! Not so much when that was not the case. See also: Christians, lions! That was more of a perceived political than a religious issue, as we see it today! "Jesus AND Jupiter" would arguably have been quite alright!
The middle ages! Oh, boy! Yes, anti-semitism central! Definitely! At least as far as Europe is concerned! Ferdinand ans Isabella did not just "liberate" Spain from the Moors (read: Muslim Spaniards of mostly North African origin - several generations ago - that is basically as though we asked black British Caribbean people to go back to Barbados; and I am hoping most of us are NOT in the BNP here!), they also did not take too kindly to Jews! Nor did anyone else in medieval Europe. "Blood libel" and "well poisoning" originate here!
In the meantime, and within the general context of "people fucking suck": the 8th century CE saw the establishment of Islam as a religion - and (I AM an atheist, and this matters!) - draw heavily upon both Judaism and what were arguably some fringe Christian movements (i.e. heretics). And, going by its canon, a lot of Islam is a lot more enlightened on the subject of "Christians and Jews" than what medieval Christianity took as a view of its fellow Abrahamitic religions. Undoubtedly, someone will immediately be along to quote some of the more icky passages in a second, but: on balance, if you had to pick you most certainly would want to be a Jew in medieval, moorish Andalus over a Christian in Rome under Nero (that whole "human candle" thing may be biasing me here --- but that is apparently thought to be accurate by modern historians! Screw that! I WILL fight the lions! Just: do not candle me!).
And now, I have spent a lot of lines and words on the things I just meant "were not that important" in the grand scheme of things!
Renaissance and Enlightenment Europe REALLY went to town on the anti-semitism. 19th century Europe is when the social construct of "race", and thus racially coloured / motivated anti-semitism becomes a thing. We basically have these people to blame for "Jews have long noses and really like money*" - and all the horrors that followed.
What about Arabs, specifically Palestinians, then? Well, some 90% of the historical anti-semitism throughou the 20th century you will find is "actually a lot nicer than the Europeans" or "literally adopted from the Europeans", if we are going to be fair!
But also: yes, some >90% of Palestinians are arguably somewhat anti-semitic, at least. And this one, again, is not that straightforward: if someone controls your every move (putting it mildly), you will probably hate them! And if that same someone also happens to say "me = my religion = my ethnicity = my state" all the time, you may come to hate religion, ethnicity, state, ... I personally do not agree - but I also genuinely do not expect people to take a degree in sociology, political science, or philosophy to read a bloody press release!
The reverse is also true, starting with your typical Israeli calling Palestinians "Arabs". Tunisians are Arabs, too, as are Iraqis! Neither have a stake in wanting to live in Jenin. There IS such a thing a a distinct Palestinian national identity! Perhaps, the creation of Israel was, literally, a major factor in making it so (which would be ironic, but I suspect it was!). And I have genuinely heard as much hate speech (just read headlines from today ... "filthy animals" - WTAF?! I think you mean "humans, whose political opinions I have some serious beef with" ... hopefully!) from Israelis towards Palestinians as vice versa - if not more**)
- yes, Jews etablished "banks" (or, at least: the predecessors of what we know as them today) in Europe - that IS, in fact, and was even then, a very good for business Idea ... it is just: it is Christian usury laws, that led to this. Not Jews. Never mind Muslims!
** Mandatory disclaimer: some 80% of Palestinians I personally know are academics - I would bloody HOPE they are capable of a reflected take!
