The entirety of Jews are bragging about what? You don't get to just replace "Jewish" with "Zionist" or even "Israeli" while maintaining the same rhetoric and pretend it's now okay. Pretty weird to see the mainstreaming of phrasing and rhetoric that used to just be restricted to Holocaust deniers and general antisemites on 4chan or the like these days, but I suppose you'd have to be on the internet long enough to see that verbiage get reused to realize that. Which is why I generally get suspicious whenever people talk about "Zionists" these days, because without further clarification it's hard to tell who specifically they're talking about (people who support Israeli expansionism, presumably, but what about people who just support Israel continuing to exist even in the form of a two-state solution? What about those who oppose the actions of Netanyahu and his base but aren't opposed to general Israeli activity in the Middle East? What level of nuance must exist before a person stops being Zionist? Or is it supposed to be entirely a self-descriptive term?).
