Hamas is an evil terrorist organization. I don’t think anyone here is saying otherwise, and I assume that’s a truth you fully agree with.
So we all agree, they’re evil. How does that excuse the killing of Palestinian civilians? It would be great if the terrorists thought about the good of their fellow man, but we’ve all recognized that they’re bad guys, so it’s pretty expected they’re not going to do what’s good for their people, but that doesn’t change that a bunch of people who are not Hamas are currently being killed by Israel.
