This very much seems to me, so far, to be rather pro-Jewish, rather than anti-fascist. I was thinking that while reading above, and then saw that the work was funded by the American Jewish Committee. There are several reasons I thought this, one of which was the use of the term antisemitism liberally. Semitism is or having to do with people speaking semitic languages, such as Arabic and Hebrew. The vast majority of Semites are Arabic speakers, such as those being slaughtered to day in Gaza.
You never hear Muslims complaining of antisemitism. The people committing the slaughter of the Semites in Gaza do complain constantly of antisemitism, although genociding and ethnically cleansing Gaza of it's semitic population is horrifically antisemitic. It is only Jews that complain of antisemitism, perhaps more properly Zionists, who constantly claim that Judaism is Zionism, which is blatantly false.
So, I don't think antisemitism exists. No one is prejudiced against speakers of semitic languages. No one lumps Hebrew speaking Jews and Arabic speaking Muslims into a basket and holds irrational unfavorable views of those peoples. It's a deceptive term, meant to conflate opposition to Zionism with racism against Jews and Muslims, in order to trick people that oppose Zionism. I do not have a problem with Judaism anymore than I do Islam, Christianity, or Atheism, but the term antisemitism conflates Judaism and Islam, so the people using it as a codeword for antizionism are able to larp as not racist, and not supremacist, because they lump in their primary victims, Muslims, into the term antisemitism, which is actually antizionism, and that is a blatantly false imposition because Muslims are ubiquitously opposed to Zionism that slaughters them wholesale. I do have a rational and well supported opposition to Zionism, which is racist, supremacist, terrorist, brutally violent, and genocidal, as we can see from events ongoing in Gaza.
I think Zionists create antisemitism to use it to oppose antizionism, which is deceptive and something people that don't want to be played for fools should oppose. Because Zionism larps as Judaism, it becomes difficult to separate Zionists from Jews, unless the Zionists aren't Jews, but are Christians, Atheists, or Talmudists (or worse, Sabbatean/Frankists), which together are the bulk of Zionists in fact. It's a sneaky ploy that is typical of the quality of Zionist tactics and strategies, and designed to ride on the shirt tails of Judaism, while leaving Jews to take the blame for the evils of Zionism (and Talmudism, which is a manifesto of evil).
Thanks!
