Until the last panel, I didn't even read that character as Jewish. But rather just a hate filled fascist wrapped in the flag of whatever religion is convenient to their current goal. It looks more like trump than a sewer rat.

Worth pointing out that 'they' here is the Jewish artist Eli Valley. A lot of his work is about subverting the language of antisemitism e.g. he'll use typical tropes to depict gentiles, and then e.g. the Jewish figure here has a tiny nose. It's certainly edgy at times, but he's engaging with the terms of his own oppression as a Jew

One of the protesters is also jewish and is drawn normally.

I didn't see that guy as a sewer mutant type guy. Just as a heckler type guy that has a furious facial expression. But that's just my opinion of course. Faces get drawn weird sometimes in comics.

Comic negative about israel

Person shows up saying how he is very concerned looking for nonexistent stereotypes in the comic that could be interpreted as anti-Semitic only by Zionists.
