It just leads me to wonder, why do people do this? Life's already hard enough without these assholes compounding things for whatever reason they have (and I'd like to know what motivates them to do all these things).
I mean...You've pretty much hit it: Assholes can be motivated by being assholes and exist with no regard for ethnic background. (Though, in particular, there is a bit of a wonky history in the US of Jews being 'white' for some standards, but not for others--US racial history kind've throws a wrench in a lot of this stuff and makes self-identification awkward or weird at times, the easy example being 'White hispanic' as someone has mentioned, or the ubiquitious 'African-American' arising because former slaves and their descendents don't know any kind of specific part or tribe of Africa they hail from).
I'm given to understand there are some far-minority strains of Judaism which might embody that 'asshole' characteristic because of a belief in inherent superiority or some bizareness, but...Well, the historical blood libel and mass criticism of Jews and Judaism for imaginary things, and the consequences that had, tends to be something one needs to account for in any critique. Which is something a lot of people aren't that good at (I'll note--you included in this one, not pinpointing specific strains or individuals beyond one random person is not a good look), and the popularity or widespread use of such poorly-phrased 'criticism' of Jewish ideologies by folks who are anti-semitic and using them as a way of hitting Jews in general (or the state of Israel, which is a popular one to go after with similar tactics) instead of earnestly looking to point at failures in the philosophy of fringe or minority extremists.
Much the same pattern exists in hard-right circles with regards to Islam--though there might
sometimes be some attempt at specifying 'wahhabism' or other extremist strains, sometimes--and with the fedora-tipping brigade with regards to Christianity (though there might sometimes be some attempt at specifying 'born-again evangelical televangelism' or other extremist strains, sometimes). Judaism and Jews don't seem to usually benefit from even the attempts at critics being specific or focused in similar manner (I had to look up a reference to
'the Revolt' and Jewish extemism because I've never heard anyone criticize or identify them in particular as opposed to assigning radical and uncommon beliefs to 'Jews' in general--to be perhaps excessively charitable maybe that's from mere ignorance and lack of terminology separating or distinguishing them in Judaism beyond the generic 'fundamentalist' or 'extremist' statements...But I think that's being excessively charitable, because Jews remain a bizarrely popular target for hate and criticism based solely on status as 'Jewish' instead of actual asshole behavior or belief).
