I think there's some tacit concession that Israelis won't be happy until the hostages are dead and properly martyred.

Sadly if you don't wish for this yourself you're being antisemitic; it's only Westerners who are stupid enough to think that tearing down posters of the hostages is magically antisemitic; in the real world, in Israel, it's the average Israeli tearing down posters of the hostages, so if the Israelis are showing this kind of animosity for the hostages, then it's only right that we should too.

After all, antizionism is antisemitism.
