If they are elderly, that puts the lie to the “IDF is committing genocide” narrative. The elderly do not breed. But if you are Hamas, and want to do a false flag to incriminate Israel, the elderly would be whom you’d slaughter, because they’re expected to die soon anyway. So you tell the next of kin they died of Covid, and the remains had to be cremated to prevent contagion. Done and done.
That Gaza is not down to its last few thousands puts the lie to the “the IDF is committing genocide” narrative. Even if Israel were being badly behaved no one with any sense thinks that they are committing genocide, and those that say so are either gullible imbeciles or deliberate liars.
