Yes; I would agree that behavior of those people is egregious.

But I'm not actually certain you want to be on record as saying that the behavior of the majority of a group means we can judge every member of that group by it, do you? Reviving prejudicial practices feels like the wrong bandwagon.

Which is terrible of Israel and rightly deserves criticism; I miss how it necessitates us, as individuals, to be alright or comfortable with the conflation of all Jewish people, as a whole, with holding unified belief, particularly in a world with a very long history of prejudice that argues they're a wily group that works in unified concert to achieve singular ends.

While there are a few people here, at the very least, unconsciously conflating the two, I think the point kerrigan778 is pointing out is that writing this message only on kosher meals is clearly making an assumption that a Jewish person is pro- the current genocide in Gaza.

Sure, it's not as bad as genocide, most clearly, but it's still a form of prejudice and can put a person at risk (we could reasonably justify morally putting something that would cause damage or sickness in the food of a genocider but, if you're targeting ends up including people who aren't in support of the genocide, you're hurting those people – too –, now).

And, given the history of hatred against Jewish people (and it's uptick starting in 2016), I'd argue it's something we should also be concerned about and stopping. I think that was their only point.
