If you’re going to claim that Israel is killing children because Hamas is hiding in schools and there aren’t schools, that’s a really silly claim.
And if there were schools, you’re claiming that Israel needs to bomb schools filled with children in self-defense. I don’t know that you’re going to find too many people sympathetic to that argument.
I sincerely hope you aren’t a parent if you feel children are so disposable.
Also, if you have to kill children in the name of self-defense, maybe you don’t have anything worth defending.
