When it came out that Israel was systematically sodomizing detainees with nightsticks, they had protestors come out in favor of the guards. It's still ongoing, all charges have been dropped. Nobody is scandalized by it.
Even ignoring the fact that protests do not imply popular support, there is no comparison as 9/11 did not include widespread sexual violence and ongoing hostage rape was still going on at the time this happened.
So even if this seemed terrible to most Israelis, it was hard to find someone who will publicly defend a rapist from rape in jail
And that's from a human rights body, and from its representative to the Israeli/Palestinian conflict
