I'd go one step further and say it's disrespectful to actual victims of violent antisemitism (such as holocaust survivors and their relatives) when their suffering is co-opted into blanket support for the military actions and war crimes of a genocidal ethnostate. As if regular people are just as bad as Hitler when they dare to question Israel's methods such as the use of white phosphorous, the indiscriminate targeting of hospitals and medical staff, complete lack of regard for collateral damage as displayed when they'll bomb 30 civilians for a chance to kill one terrorist (America is also dogshit in this regard, please keep in mind) and frequent statements from their government which consistently paint Palestinians as subhuman savages, 'children of darkness' destined only to be annihilated by the 'children of light'.

That's the shit we have a problem with. It actually has nothing to do with their ethnicity, and only has to do with their religion insomuch as they use it as a justification for racism and genocide. That's also a similarity to Islam- it's not the religion itself that's irredeemable, but rather what its followers choose to do with it.
