Isreal has been caught in so many bald-faced lies that at this point, in spite of Hamas' history of being absolutely horrible people, we're still forced to step back from every single claim made about them now and say "But did they really?"
Even if the claim is true, the decision to focus on reporting about specific, morally reprehensible actions by Hamas is a deliberate choice that serves to obfuscate and distract from the sheer unbelievable scale of the atrocities that Isreal is committing and has been committing in Palestine for decades.

Do I find the claim believable? Absolutely. But we have to step back and interrogate the intention behind making it. This is an attempt by the Biden administration to control the conversation, because they know that voters are pissed at them for their unflinching support of Isreal, in spite of their endless litany of war crimes. They're not willing to give up that support, so instead they have to find any way they can to turn the conversation away from what Isreal is doing.

This is propaganda. Whether it's true or not, its purpose is to control the way people think about the choices their government is making. And that's why people are downvoting it.
