If the person that did this was high at the time, i’d buy that, otherwise no.
Comedy is all about context, that joke works because it deliberately crosses the line of acceptability, it could be safely deployed in a context where everyody understands that nothing being said can be taken seriously and all bets are off. It requires buy in, you actually have to feel a bit bad for making the joke, otherwise, the joke becomes too literal, it actually becomes about killing jews.
This was deployed without context, without buy in and indiscriminately, the joke itself was presented as funny because its true rather than its funny because its mean. The best argument you can make is that the person who did this was unthinking, but that is actually more damning, because then you must accept that the person who put this out there expected it to be funny in and of itself.
Its sad but saying someone’s stupid for making a joke still means that person is stupid and thus incapable of offering defense. Maybe a heartfelt apology, an admission that something was learnt here would let us judge intent fairly, otherwise, the action itself can only be mean spirited and hateful, even without and especially because we cannot judge intent, only appropriateness.
