What evidence you need, Hamas themselves said they have taken hostage, and there are tons of video showing them taking hostage, and the leader of Hamas publicly saying they will kill a hostage every time Israeli move in for a strike, no matter how polite you are asking to take your hostage captive it still a crime and you can't do that in war.
I have no issue how you see things, you probably think that's justifiable, and I understand why. The issue here is, if you refused to see that for what it is, then the west will refuse to see that for the Israeli, then it just goes into the downward cycle. Because you are saying the Israel did not distinguish between Hamas and regular Palestinian, but then aren't you are doing the same between Israel civilian and Israeli military?
