Saying "Hamas started it" ignores years and years of history and pretends that October 7th came out of nowhere
As for hostages, it's very convenient to ignore the thousands of Palestinians held in Israeli prisons for offences such as "raising the Palestinian flag"
Or this:
A 2023 report by Save the Children found widespread use of physical, emotional, and sexual abuse against Palestinian children in Israeli military detention. The report found that among detained children, 86% were beaten, 69% were strip searched, 60% spent time in solitary confinement, 68% were denied any healthcare, and 58% were denied visits or communication with family
And given, therefore, that the IDF have been holding thousands of Palestinian children captive, beating them and sexually abusing them, then all the arguments put forward that justify Israels current attacks on Gaza, also justify October 7th.
Now I don't personally believe it does justify October 7th. But I also dont believe Israel are justified in their actions. But if its okay to kill 1000s of Palestinians because Hamas started it, then maybe consider what it's okay to do when Israel is taking your children prisoner and abusing them? what would you do?
