Well, the prime minister, the finance minister and the head of defense all have said similar things over there in Israel. At some point you have to believe that what they are saying and their actions are speaking for themselves and their words and actions are saying "no one is innocent and even if they were we are still going to kill them all so we can get the land."
I mean, it's kinda like judging America based on Pat Robertson, the Westboro Baptist Church, Steve Bannon, Steve Miller, and Trump.
Yes, we should beleive people like Trump when they say how awful they are. The fact that he was elected and is the presumptive Republican nominee says a lot about the American right, right now. But it definitely doesn't mean that Americans in general are awful people.
Yeah, although if the American state were sponsoring said crazy preacher it would be an issue. The Rabbi and his Yashiva are sponsored by the Israeli government as the article makes clear.
