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.
